Pls help i need it now pls i will give 20points pls answer it correctly pls Solve the system y = -x + 7 and y = -0.5(x - 3)^2 + 8

Step-by-step explanation:

-x+7=-0.5(x-3)^2+8

-x+7=-0.5x^10 -4.5^10

am I getting ...!?

(-1,6) and (-7,0)

Step-by-step explanation:

-x+7=-0.5(x-3)^2+8

times both sides by -2

2x-14=(x-3)^2-16

expand

2x-14=x^2-6x+9-16

add 14-2x to both sides

0=x^2-8x+7

factor

0=(x-7)(x-1)

set to zero

0=x-7

7=x

0=x-1

1=x

so find y

y=-x+7

y=-1+7

y=6

or

y=-7+7

y=0
