A large pizza has a diameter of 35cm. 2 large pizzas cost $19.99 A medium pizza has a diameter of 30cm. 3 medium pizzas cost $24
insens350 [35]
So first we need to find the area of both using a=3.14*radius*radius

to find the radius we need to divide 35 by 2 (large) and 30 by 2 (medium)

lets do the large first since the raidus is 17.5 we put it into a=3.14*17.5*17.5

and then we get 961.63, for the medium we do a=3.14*15*15 which is 706.50

now for the large 961.63 * 2 is 1923.26 and the price is 19.99 

for the medium we do 706.50 *  3 which is 2119.5 and costs 24.99

So the medium pizzas are a better deal

Use the vertex
xxTIMURxx [149]

Answer:

Step-by-step explanation:

Let the quadratic function be

y=a(x+4)²-1

∵(-7,8) lies on it.

8=a(-7+4)²-1

8+1=a(-3)²

9a=9

a=9/9=1

so quadratic function  is

f(x)=1(x+4)²-1

or

f(x)=x²+8x+16-1

so quadratic function is

f(x)=x²+8x+15

How to do this equation y=2x-10 and 2y=x-8
Lana71 [14]

Answer:

y=2x-10

2y=x-8

since the second equation equals 2y and the first is y that means the first equation times 2 equals the other one

4x-20=x-8

-x

3x-20=-8

+20

3x=12

x=4

then lets just plug it in

2y=4-8

simplefy

2y=-4

y=-2

(4,-2)

Hope This Helps!!!
