a)

b) independent variable: x - number of DVDs rented

dependent variable: y - the monthly cost of rent of x DVDs

c) $26

Step-by-step explanation:

Question:

Your DVD membership costs $16 per month for 10 DVD rentals. Each additional DVD rental is $2.

a. Write an equation in two variables that represents the monthly cost of your DVD rentals.

b. Identify the independent and dependent variables.

c. How much does it cost to rent 15 DVDs in one month?

Solution:

Let x be the number of DVDs rented, and y be the monthly cost of rent of x DVDs.

a) For the first 10 DVDs you should pay $16 and for the next (x - 10) DVDs you have to pay additional $2 per DVD.

Then the total cost is

b) Independent variable is x, dependent variable is y (the cost depends on number of DVDs rented).

c) If x = 15, then

It will cost $26 to rent 15 DVDs.

step-by-step explanation:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
