Find the equation of the line that contains the given point and is parallel to the given line. Write the equation in​ slope-intercept form, if possible.
(1,-1) y=4

Answers

Answer 1

The equation in​ slope-intercept form is y = 4x - 5

What is the slope-intercept form?

One of the most popular ways to represent a line's equation is in the slope-intercept form of a straight line. When the slope of the straight line and the y-intercept are known, the slope-intercept formula can be used to determine the equation of a line.

What is the slope-intercept formula?

the slope of a line joining two points (x, y) and (x₁, y₁) is, m = (y - y₁)/(x - x₁)

Here we have,

x₁ = 1

y₁ = -1

m = 4

then, by applying the slope-intercept formula, we get

m = (y - y₁)/(x - x₁)

4 = (y + 1)/(x - 1)

4(x-1) = (y+1)

4x - 4 = y +1

y = 4x - 5

Hence, The equation in​ slope-intercept form is y = 4x - 5

Hi there!

The two angles are alternate-interior angles, so:
∠A ≅ ∠B

6x + 18 = x + 93

Solve for x. Subtract x from both sides:

5x + 18 = 93

Subtract 18 from both sides:

5x = 75

Divide both sides by 5.

x = 75/5 = 15°

Now, solve for angle B by plugging in this value into the equation.

the value of y varies jointly with x and the square of z, and y=90 when x=5 and z=3. find the equation represents this relationship

Answers

Answer:

Step-by-step explanation:

If y varies jointly with x and the square of z, we can express this relationship as:

y = kx z^2

where k is the constant of variation. To find the value of k, we can use the given information that y = 90 when x = 5 and z = 3:

90 = k(5)(3)^2

Simplifying, we get:

90 = 45k

Dividing both sides by 45, we get:

k = 2

Now we can substitute this value of k into our equation to get:

y = 2xz^2

Therefore, the equation that represents the relationship between y, x, and z is:

y = 2xz^2

There are 55 black balls and 88 red balls in an urn. If 44 balls are drawn without replacement, what is the probability that no more than 11 black ball is drawn

Answers

Answer:

\(Probability = \frac{70}{143}\)

Step-by-step explanation:

Given

\(Black = 5\)

\(Red = 8\)

\(Total = 13\)

To solve the required probability, we need to determine the number of available selections:

There are two possible scenarios;

1: All 4 selections are red.

2. 1 selection is black, while 3 others are red

Scenario 1: All Red

\(^8C_4 = \frac{8!}{(8-4)!4!}\)

\(^8C_4 = \frac{8!}{4!4!}\)

\(^8C_4 = \frac{8*7*6*5*4!}{4!4!}\)

\(^8C_4 = \frac{8*7*6*5}{4!}\)

\(^8C_4 = \frac{8*7*6*5}{4*3*2*1}\)

\(^8C_4 = \frac{1680}{24}\)

\(^8C_4 = 70\)

Scenario 2: 1 Black, 3 Red

Selecting Black:

\(^5C_1 = \frac{5!}{(5-1)!1!}\)

\(^5C_1 = \frac{5!}{4!1!}\)

\(^5C_1 = \frac{5*4!}{4!*1}\)

\(^5C_1 = 5\)

Selecting Red:

\(^8C_3 = \frac{8!}{(8-3)!3!}\)

\(^8C_3 = \frac{8!}{5!3!}\)

\(^8C_3 = \frac{8*7*6*5!}{5!3*2*1}\)

\(^8C_3 = \frac{8*7*6}{6}\)

\(^8C_3 = 8*7\)

\(^8C_3 = 56\)

Number of Selection = 5 * 56

\(Selection = 280\)

Total Available Selection is calculated as thus:

\(Available\ Selection = 70 + 280\)

\(Available\ Selection= 350\)

Next, is to calculate the number of possible selections:

i.e 4 balls out of 13

This is calculated as:

\(^{13}C_4 = \frac{13!}{(13-4)!4!}\)

\(^{13}C_4 = \frac{13!}{9!4!}\)

\(^{13}C_4 = \frac{13 * 12 * 11 * 10 * 9!}{9!4*3*2*1}\)

\(^{13}C_4 = \frac{13 * 12 * 11 * 10}{4*3*2*1}\)

\(^{13}C_4 = \frac{17160}{24}\)

\(^{13}C_4 = 715\)

\(Probability = \frac{Available\ Selection}{Possible\ Selection}\)

\(Probability = \frac{350}{715}\)

\(Probability = \frac{70}{143}\)

3(x + 2) + 4 = 3x + 9 prove this is not an identity

Answers

The linear equation has no solutions, thus, it is not an identity.

How to prove that the equation is not an identity?

An equation is an identity if it is true for any value of x.

So, if here we can find a unique solution ( or not solutions at all) for the linear equation, then we will prove that the equation is not an identity.

The linear equation is:

3*(x + 2) + 4 = 3x + 9

If we simplify the left side, we will get:

3*(x + 2) + 4 = 3x + 9

3*x + 3*2 + 4 = 3x + 9

3x + 6 + 4 = 3x + 9

3x + 10 = 3x + 9

Mary Beth uses 7/12 yards of fabric to make a pillow. How much fabric will she need? Between what two whole numbers

Answers

The range of whole numbers between which the decimal falls is 0 yards to 1 yard.

What is a whole number?

The whole number is set to positive integers including 0. i.e 0, 1, 2, 3, and so on.

To find the total amount of fabric Mary Beth needs to make a pillow, we first need to convert 7/12 yards into a decimal. To do this, we can divide the numerator by the denominator:

7/12 = 7 / 12 = 0.5833...

So, Mary Beth needs approximately 0.5833 yards of fabric to make a pillow.

To determine the range of whole numbers between which the decimal falls, we can round up to the next whole number (1 yard) and round down to the previous whole number (0 yards). Therefore, the range of whole numbers between which the decimal falls is 0 yards to 1 yard.

Cold Beans wants to make a blend of their two best coffees, Guatemalan and Jamaican coffee. The pound of Guatemalan Coffee costs $11/lb and the other one costs $5/lb. If they want the cost of a 6 pound bag of blend to be $8/lb, how much Guatemalan coffee should they use per pound of the blend?

Answers

For each pound of the blend, Cold Beans should use 3 pounds of Guatemalan coffee.

This means that in a 6-pound bag of the blend, they would use \(3 \times 6 = 18\)pounds of Guatemalan coffee.

Let's assume that x pounds of Guatemalan coffee are used per pound of the blend.

Given information:

Cost of Guatemalan coffee = $11/lb

Cost of the other coffee = $5/lb

Desired cost of the blend = $8/lb

Total weight of the blend = 6 pounds

To find the ratio of Guatemalan coffee to the total blend, we can set up the equation:

\((x \times 11 + (6 - x) \times 5) / 6 = 8\)

In this equation, \((x \times 11)\) represents the cost of the Guatemalan coffee in the blend, and\(((6 - x) \times 5)\) represents the cost of the other coffee in the blend.

The numerator is the total cost of the blend, and we divide it by 6 (the total weight of the blend) to find the cost per pound.

Now, let's solve the equation for x:

(11x + 30 - 5x) / 6 = 8

6x + 30 = 48

6x = 48 - 30

6x = 18

x = 18/6

x = 3

Therefore, for each pound of the blend, Cold Beans should use 3 pounds of Guatemalan coffee.

This means that in a 6-pound bag of the blend, they would use \(3 \times 6 = 18\)pounds of Guatemalan coffee.

To summarize, to achieve a cost of $8 per pound for a 6-pound bag of blend, Cold Beans should use 3 pounds of Guatemalan coffee per pound of the blend.

Alijah's taxable income puts him in the first tax bracket, over $8,350 but not surpassing $33,950. Hence, his tax due is a base of $835 plus 15% of the income that exceeds $8,350. This results in a total tax payable of $850. Option B is the correct answer.

Alijah's taxable income falls within the first bracket of the tax table given, being over $8,350 but not over $33,950.

This bracket requires him to pay a tax of $835.00 plus 15% of the amount over $8,350.

He has a surplus of $100 over the $8,350 threshold (i.e., $8,450 - $8,350), and 15% of $100 equals $15.

Therefore, the total tax he owes would be the fixed amount of $835.00 plus the $15.00 calculated, which sums up to $850.00.

Thus, looking at the provided options, option B ($850.00) would be the correct answer.

Keller Construction is considering two new investments. Project E calls for the purchase of earthmoving equipment. Project H represents an investment in a hydraulic lift. Keller wishes to use a net present value profile in comparing the projects. The investment and cash flow patterns are as follows: Use Appendix B for an approximate answer but calculate your final answer using the formula and financial calculator methods.

Answers

Based on the net present value profile, Project H has a higher NPV than Project E.

To compare the net present value (NPV) of Project E and Project H, we need to calculate the present value of cash flows for each project and determine which one has a higher NPV. The cash flow patterns for the two projects are as follows:

Project E:

Initial investment: -$100,000

Cash flows for Year 1: $40,000

Cash flows for Year 2: $50,000

Cash flows for Year 3: $60,000

Project H:

Initial investment: -$120,000

Cash flows for Year 1: $60,000

Cash flows for Year 2: $50,000

Cash flows for Year 3: $40,000

To calculate the present value of cash flows, we need to discount them using an appropriate discount rate. The discount rate represents the required rate of return or the cost of capital for the company. Let's assume a discount rate of 10%.

Using the formula method, we can calculate the present value (PV) of each cash flow and sum them up to obtain the NPV for each project:

For Project E:

PV = $40,000/(1 + 0.10)^1 + $50,000/(1 + 0.10)^2 + $60,000/(1 + 0.10)^3

PV = $36,363.64 + $41,322.31 + $45,454.55

PV = $123,140.50

For Project H:

PV = $60,000/(1 + 0.10)^1 + $50,000/(1 + 0.10)^2 + $40,000/(1 + 0.10)^3

PV = $54,545.45 + $41,322.31 + $30,251.14

PV = $126,118.90

Using the financial calculator method, we can input the cash flows and the discount rate to calculate the NPV directly. By entering the cash flows for each project and the discount rate of 10%, we find that the NPV for Project E is approximately $123,140.50 and the NPV for Project H is approximately $126,118.90.

Divide the numerator and denominator by the GCF to reduce a fraction. (This is also referred to as "writing a fraction in the simplest terms.") The common factors are sometimes shown to be "cancelled." It is worth noting that the result is an equivalent fraction in its simplest form.

How do you divide the numerator to the denominator by GCF?

To put it simply, we must divide the numerator (x) by the denominator (y) to simplify it. For example, after simplifying 3 6, represent it as a fraction and identify the numerator and denominator. 3 6 can be written as 3/6. Further simplification yields 1/2.

Let's pretend the fraction is a proper fraction. The denominator is the numerator. We want to reduce the fraction to its simplest form.

a) Use Numerator =Remainder* as the denominator.

Now Numerator >Remainder* b)Numerator Remainder*=Remainder** c) ••• (keep going until Remainder =0)

d) When the Remainder equals zero, the Divisor is the GCD (or GCF, as you say). GCF is a misnomer because it only deals with numbers. Only the term GCF applies to variables (with numerical values, as in algebraic expression).

Let us look at an example.

407/3367 is the fraction.

As evident, the numbers407 ,3367 does not appear to have share Divisors 2 or 3 or 5 or 7 or 11 from prima facie considerations. So we may take recourse of successive division method.

3367 ÷407 =Remainder 111 (quotient 8)

407 ÷ 111 =Remainder 74 (quotient 3)

111 ÷74=Remainder 37 (quotient 1)

74 ÷37 =Remainder 0 (ZERO )

Here 37 divides leaving Remainder zero. Therefore the GCD is 37
