Answer:
y=2.5x
Step-by-step explanation:
You already know that the cost for 1 book is $2.50, which is also the rate of change. So you just basically multiply 2.50 by 5 to get 12.50.
Answer:

Step-by-step explanation:
The volume V of the fountain is equal to:
V = L*W*h
Where L is the lenght of the fountain, W is the width of the fountain and h is the high of the fountain
We already know that h is equal to x. On the other hand, if we cut a square with side of length x, L and W are calculated as:
L = 18 - 2x
W = 12 - 2x
So, replacing L, W and h on the equation of the volume, we get:
V = (18-2x)*(12-2x)*x
Finally, simplifying the function we get:


Answer:
its 1
Step-by-step explanation:
it literly says it on the grid and its really simple
Ax+By=C , where A=0, B is positive , and C is negative
so y = - C/B (less than 0)
So answer is the last one. (y = -3)
Answer:
3 cups
Step-by-step explanation:
Assumptions: How much sugar does cost sprinkle on the brownies. Cost meant Cody
Given data:
Total of 4 cups
3/4 is sprinkled onto a plate of brownies
