Step-by-step explanation:

g(x)= -16x² + 72x + 80

Plug 2 in to check if it's correct.

g(2)= -16(2)² + 72(2) + 80

-16(4)+128+80

-72+128+80

= 136

If x-y =8 find the value of y when x=3
DedPeter [7]
Answer: y = -5

Substitute in 3 for x.
x - y = 8                            Substitution
3 - y = 8                            Subtract 3 from both sides
-y = 5                                Divide by -1 to both sides
y = -5                                Answer!

You can also check your work.
x - y = 8       
3 - (-5) = 8                  
3 + 5 = 8                        
8 = 8
