Answer:
y - 12 = 9(x - 4)
Step-by-step explanation:
The vertex (h, k) is (4, 12) and the point (5, 21) is on the graph. Assuming that this is a vertical parabola, opening up (because the coordinate 21 is greater than the coordinate 12), we insert the knowns into y - k = a(x - h)^2, obtaining
21 - 12 = a(5 - 4), or 9 = a. With a known, we can write the desired equation:
y - 12 = 9(x - 4)
Step-by-step explanation:
In this type of math equation, you have to multiply all members from the first part with the second part.

Answer:
first make everything inches so you have at least 62 inches and at most 73 inches, now create it.
Step-by-step explanation:
62<x<=73
No she can't spend $4.39 for each sandwich because if you divide 20 by 5 your quotient will be 4.
