Answer:

-3g=-4

g= \(\frac{4}{3}\)

Step-by-step explanation:

To solve this problem, first, let's remember the definitions of even and odd functions.

• A function f is ,even, if the graph of f is ,symmetric about the y-axis,.

• A function f is ,odd, if the graph of f is ,symmetric about the origin.

a) To make the function even, we must complete the graph such the graph result is symmetric about the y-axis (the vertical axis). Doing that we get:

b) To make the function odd, we must complete the graph such the graph result is symmetric about the origin (the horizontal axis). Doing that we get:

Answer:

the area of the rectangle is A=L•W

The length is 3m less than twice its width W: L+ 3m=2W...->, L=2W-3m

A=L-W

27m²=(2W-3m)-W

Answer:

60%

Step-by-step explanation:

12/20 = 3/5 = 0.6 = 60%

Hey there! To find out how much of her homework Jewel completed, all we need to do is a little math. First, let's divide the number of questions she did by the total number of questions. That's 12 divided by 20 which equals 0.6.

Now, we just need to turn that decimal into a percentage. To do that, we simply multiply 0.6 by 100, which gives us 60. And voila! Jewel completed 60% of her homework.

The inverse of the function → f(x) = 2x + 5  is → f⁻¹(x) = (x/2) - (5/2).

Inverse of a function can be calculated by following the steps mentioned below -

According to the question, the equation given is as follows

y = f(x) = 2x + 5

y = 2x + 5

Replace 'y' with 'x', we get -

x = 2y + 5

Now, solve for y -

2y = x - 5

y = (x/2) - (5/2)

Replace 'y' with f⁻¹(x) -

f⁻¹(x) = (x/2) - (5/2)

Hence, the inverse of the function → f(x) = 2x + 5  is → f⁻¹(x) = (x/2) - (5/2).

Answer:

10.5 mph

Step-by-step explanation:

To find the constant of proportionality in miles per hour, we need to divide the distance (in miles) by the time (in hours) for each of the two runs, and then take the average of the two rates.

For Monday's run:

Rate = Distance / Time = 21 miles / 3 hours = 7 miles per hourFor Wednesday's run:Rate = Distance / Time = 10 1/2 miles / 1 1/2 hours = (21/2) miles / (3/2) hours = 14 miles per hour

To find the average rate, we add the two rates and divide by 2:Average rate = (7 miles per hour + 14 miles per hour) / 2 = 10.5 miles per hour

Therefore, the constant of proportionality in miles per hour is 10.5. This means that Ashley runs at an average rate of 10.5 miles per hour during her training.

Thus, an equation to show the overall price y of renting shoes and bowling x equipment is: y=4x+b.

The task is to create an equation that use the total expense (y) and the total number of bowled games (x). Hence, the way that we will begin is by entering the knowing into the formula of slope intercept form:  y=mx+b.

Thus, we include them in the formula: y=4x+b.

14 = 4(3)+b

Find b

14 = 12+b

14 - 12=b

b = 2

Thus, an equation to show the overall price y of renting shoes and bowling x equipment is: y=4x+b.

Step-by-step explanation:

To find the percentage, we need to divide the amount of creamy peanut butter by the total amount of peanut butter. In this case, there are 443 jars with creamy peanut butter and 886 total jars.

What is 443/886? Well, you could divide it out, but you could also notice that 443 is exactly half of 886 and simplify to 1/2, which is equal to 0.5. Either way works, but one's just a lot quicker.

Next, we have to convert the decimal - 0.5 - into a percentage. To do this, we move the decimal point to the right two spots, getting us to 50, and then slap a percentage sign on there giving us a final answer of 50%.

Step-by-step explanation:

10x+14 = -2x+38  add 2x to both sides

10x +2x +14 = -2x +2x +38

10x +2x +14 = 38 subtract 14 from both sides

10x +2x +14 -14 = 38 -14

10x +2x = 38 -14 combine like terms

12x = 24 divide both sides by 12

12x/12 = 24/12

x =2

Answer:

x = -2

Step-by-step explanation:

10x + 14 = -2x + 38

Subtract 14 from both sides:

10x + 14 - 14 = -2x + 38 - 14

10x = -2x - 24

Add 2x to both sides

10x + 2x = 2x - 2x - 24

12x = -24

Divide both sides by 12

12x/12 = -24/12

The XOR (exclusive or) of two events A and B can be defined as the set of all elements that are in either A or B but not both.

The probability of this event, P(AAB), can be calculated by summing the probabilities of A and B and subtracting twice the probability of the intersection of A and B, as follows:

P(AAB) = P(A) + P(B) - 2P(AnB)

This can be illustrated with a Venn diagram, where A and B are represented by two overlapping circles. The intersection of A and B, AnB, is represented by the overlapping region, and the symmetric difference, AAB, is represented by the non-overlapping regions of A and B.

The probability of AAB can then be calculated by adding the area of the two non-overlapping regions and subtracting twice the area of the overlapping region.

a) The discount on the loan is $1,862.

b) The amount of money the borrower received on the discount loan is $11,438.

c) The true interest rate paid on the discounted loan is 4.1%.

A discount loan is a type of loan in which the interest (cost of borrowing) is deducted upfront or at the time the loan is granted.

The implication of getting a discount loan is that the amount received is less than the principal amount because the grantor has reduced it by interest and other fees (finance charges).

The principal = $13,300

Discount rate = 3¹/₂%

Time = 4 years

Discount = $1,862 ($13,300 x 3.5% x 4)

Amount received = $11,438 ($13,300 - $1,862)

Real interest rate = 4.1% ($1,862/$11,438 x 100)/4
