Answer:

7)  Domain:  (-∞, ∞)

    Range:  [-1, ∞)

8)  Domain:  (-∞, ∞)

    Range:  (-∞, ∞)

Step-by-step explanation:

Interval notation

( or ) : Use parentheses to indicate that the endpoint is excluded.

[ or ] : Use square brackets to indicate that the endpoint is included.

Domain & Range

The domain is the set of all possible input values (x-values).

The range is the set of all possible output values (y-values).

From inspection of the graph, the line is continuous.

The arrows either end of the line indicate that the line continues indefinitely in those directions.

Therefore, the domain of the relation is unrestricted:  (-∞, ∞)

From inspection of the graph, the minimum y-value is y = -1.  

The end behavior of the relation is:

\(y \rightarrow + \infty, \textsf{as } x \rightarrow - \infty\)

\(y \rightarrow + \infty, \textsf{as } x \rightarrow +\infty\)

Therefore, the range of the relation is restricted:  [-1, ∞)

From inspection of the graph, the line is continuous.

The arrows either end of the line indicate that the line continues indefinitely in those directions.

Therefore, the domain of the relation is unrestricted:  (-∞, ∞)

The end behavior of the function is:

\(y \rightarrow + \infty, \textsf{as } x \rightarrow - \infty\)

\(y \rightarrow -\infty, \textsf{as } x \rightarrow +\infty\)

Therefore, the domain of the relation is unrestricted:  (-∞, ∞)

Step-by-step explanation:

so, we calculate the perpendicular slope, and then we start with the point-slope form (since we were given a specific point of the line), and transform into the regular slope-intercept form.

the slope in

y = 2x + 2

is the factor of x : 2 or 2/1

the perpendicular slope is turning this upside down and flips the sign : -1/2

the point- slope form is

y - y1 = a(x - x1)

"a" being the slope, (x1, y1) being the point.

y - 9 = -1/2(x - -2)

y - 9 = (-1/2)x - 1

y = (-1/2)x + 8

Answer:

There are 32 possible combinations when buying a home in this neighborhood.

Step-by-step explanation:

We need to use a combination to find our answer. There are 5 options, and we need to find how many combinations can be made of some, all, or none.

We use the permutation (combinations in no specific order) formula to find these: C(n,r)=n!/r!(n-r)! (sometimes C(n,r) is written as nCr, and in a calculator this is what you would see) , where n is the number of items to make a combination from (in this case n=5), and r is how many items are in the combination (in this case 0,1,2,3,4, or 5). Note that 0!=1.

Now we add our possible combinations: 1+5+10+10+5+1=32

So, there are 32 possible combinations when buying a home in this neighborhood.

The correct answer is d. provided net cash of $1,227.

The net loss of $17,915 is an outflow of cash, which means that it used net cash. However, the other changes listed in the question are also changes that affected net cash, and they had the opposite effect of the net loss.

The decrease in accounts receivable of $5,094 is an inflow of cash because it represents a reduction in the amount of money that the company is owed. The increase in inventory of $8,342 is an outflow of cash because it represents an increase in the amount of money that the company has invested in inventory. The increase in accounts payable of $15,567 is an inflow of cash because it represents a reduction in the amount of money that the company owes to its creditors. The recording of depreciation expense of $6,823 is an outflow of cash because it represents a non-cash expense.

When you consider all of these changes together, you can see that the net effect on cash was an inflow of $1,227. Therefore, the correct answer is d. provided net cash of $1,227.

The true statement for the function p(x) is p(-2) and p(0) cannot be compared as p(0) is undefined. Option D is correct.

The given function is a logarithmic function and it is undefined at x = 0.

First, let us understand the logarithmic function:

A logarithmic function is a function of the form which is read as “ y equals the log of x, base b” or “ y equals the log, base b, of x.” In both forms, x > 0 and b > 0, b ≠ 1.

We are given:

p(x) = log 5x

substitute x = 0 in the above equation, we will get;

p(0) = log 5 × 0

p(0) = log 0

p(0) = undefined

Thus, the true statement for the function p(x) is p(-2) and p(0) cannot be compared because p(0) is undefined. Option D is correct.

Answer:

Second option

Step-by-step explanation:

Given the following question:

We are given four choices and we need to determine which choice is a rational number. In order for any integer to be a rational number you have to be able to write it as a fraction.

In this case, options one and four are immediately excluded since they are repeating decimals. They cannot be written as a fraction which leaves us with the second option or the third option.

\(\sqrt{36}\)
\(\sqrt{36} =6\times6\)
\(=6=\frac{6}{1}\)
\(=\frac{6}{1}\)

Your answer is the second option or "sqrt36."

Answer:

99.9 \(cm^{2}\)

Step-by-step explanation:

Given, AB=13 cm, BC=4 cm

AC is the diagonal of parallelogram ABCD.

Also AC=16 cm

We know, △ABC≅△ACD     [S−S−S Congruence]

Also, area of parallelogram ABCD = Area of △ABC + Area of △ACD

                                            = 2 × Area of △ABC

                                            = \(2\sqrt{s(s-13)(s-4)(s-15)}\)

         \(s= \frac{13+15+4}{2}\)                 = \(2\sqrt{16(16-13)(16-4)(16-15)}\)

             = 16                          = 99.9

Answer:

  (x, y) = (5, 4)

Step-by-step explanation:

Subtracting the second equation from the first eliminates the x term.

  (4x +6y) -(4x +2y) = (44) -(28)

  4y = 16 . . . . simplify

  y = 4

Using the second equation to find x, we have ...

  4x +2(4) = 28

  x + 2 = 7 . . . . . . divide by 4

  x = 5 . . . . . . . . . subtract 2

The solution is (x, y) = (5, 4).

The value of angle x and angle y is determined as 78⁰ and 115⁰ respectively.

The value of angle x and angle y is calculated by applying principle of angles formed by parallel lines as follows;

The value of angle adjacent x = 102⁰

The value of angle x   is calculated as;

x = 180 - 102 ( sum of angles on a straight line)

x = 78⁰

The value of angle y is calculated as follows;

y = 115⁰ (corresponding angles are equal)

Thus, the value of angle x and angle y is determined as 78⁰ and 115⁰ respectively.

Answer:

48 square feet

Step-by-step explanation:

First, make an equation for the perimeter. W is the width and since the length is three times the width it is 3W. W+3W+W+3W=32. Add like terms and you get 8W=32. 32 divided by 8 is 4 so the width is four. 4x3 is 12 so the length is 12. you get area by multiply length and width so 12x4 is 48.

28x + 44y = 964.40

21x + 33y = 723.30

Let's multiply the first equation by 4 and the second by -4

84x + 176y = 3857.6

-84x - 132y = -2893.2

Add the equations together.

0 + 44y = 964.4

Simplify

44y = 964.4

Divide both sides by 44

y = 964.4/44

Since we have the value of y, let's plug 964.4/44 into y for the first equation.

28x + 44(964.4/44) = 964.40

Simplify the left side

28x + 964.4 = 964.4

Subtract 964.4 from both sides

28x = 0

Divide both sides by 0

x = 0

In conclusion,

y = 964.4/44

x = 0

The value of x in terms of y is,  x = y/2 + 1/2.

What is an equation?

Two expressions joined by an equal sign form a mathematical statement known as an equation. An equation is, for instance, 3x - 5 = 16. We can solve this equation and determine that the value of the variable x is 7.

Consider, the given equation

y = 2x - 1

We have to find value of x from the given equation.

Let,

y = 2x - 1

Add 1 on both sides,

y + 1 = 2x - 1 + 1

y + 1 = 2x

Divide both sides by 2,

(y + 1)/2 = 2x/2

(y + 1)/2 = x

x = (y + 1)/2

x = y/2 + 1/2

Hence, the value of x in terms of y is,  x = y/2 + 1/2.

Answer:

  (d)  (1, 2)

Step-by-step explanation:

You want to know which of the given points satisfies the inequality.

We find it easiest to plot the given points on a graph of the solution. This shows us that (1, 2) is a solution to the inequality. (It lies in the solution area.)

__

Additional comment

Another way to choose the answer is to try each of the points in the inequality.

If you can visualize the boundary line (without plotting it) as a line with positive slope and a y-intercept of 2, you can more readily reject the first choice and accept the last choice. (0, 3) is above the y-intercept, and (1, 2) is to the right of it (in the solution space).

You may also recognize the x-intercept will be -3, so the second choice lies above the boundary line.

We know this because if its 9000 m in 30 minutes, we can do 9000 x 2 and get 18,000m for an hour.

The evaluated function values are g(-3) = 11, g(5) = 11, g(a) = 11 and g(a+h) = 11

A composite function is a function that results from combining two or more functions. It is created by using the output of one function as the input of another function.

The function g(x) is defined as g(x) = 11, which means that the output of the function is always 11, no matter what value of x is inputted.

i.e. the function g(x) = 11 always returns the value 11, regardless of the input.

Therefore, we have:

g(-3) = 11

g(5) = 11

g(a) = 11

g(a+h) = 11

So, regardless of the value of a or h, the function g(x) will always return 11.
