Donnie is considering two different DVD rental stores, both of which have a one-time membership
fee and a fee per rented DVD,
The cost for renting DVDs at the first store is shown
below:
Number of
DVDs rented
Cost (5)
1
5.50
2
7.00
3
8.50
The cost for renting DVDs at the second store is
modeled by the linear function c = 5+ 2d where dis
the number of DVDs rented and c is the cost.
Part A: Which store charges more for each DVD rented? Explain in words how you know
Part:b Which store charges a higher membership fee to begin renting DVD's. Explain in words how know,
Part : Which store charges more for renting 6 DVD'S? Show your work

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer

she will most likely have 33  

step-by-step explanation:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
