What is the vertex form of this and how do you graph this

set it up like a y= equation.

which would be y=-x^2+7

to find the vertex, you substitute the 0s.

so 0=-(0)^2+7

-0^2=0

0+7=7

0=7

(0,7)

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6

i think it is c hope that
