Answer:

b=a/h

Step-by-step explanation:

Answer:

You have to divide both sides by h, in order to make b the subject :

A = bh

A \div h = bh \div h

\frac{A}{h}  = bh \times  \frac{1}{h}

\frac{A}{h}  = b

b =  \frac{A}{h}

Y=x^2+bx+c;(-2,3)
Maksim231197 [3]
<h3>Answer:  b = 4 and c = 7.</h3>

===============================================

Explanation:

Comparing y = x^2+bx+c to y = ax^2+bx+c, we see that a = 1.

The vertex given is (-2,3). In general, the vertex is (h,k). So h = -2 and k = 3.

Plug those three values into the vertex form below

y = a(x-h)^2 + k

y = 1(x-(-2))^2 + 3

y = (x+2)^2 + 3

Then expand everything out and simplify

y = x^2+4x+4 + 3

y = x^2+4x+7

We see that b = 4 and c = 7.

inysia [295]

Answer:

tshirts of $72=72/8

=$9

2nd way: Cost ($) 8 72

T shirts 1 x

8/1=72/x

by cross multiply

x=72/8

x=9
