Answer:
23x2+8xy−57y2
Step-by-step explanation:
(5x)(5x)+(5x)(7y)+(−7y)(5x)+(−7y)(7y)+−2x2+8xy+−8y2
=25x2+35xy+−35xy+−49y2+−2x2+8xy+−8y2
Combine Like Terms:
=25x2+35xy+−35xy+−49y2+−2x2+8xy+−8y2
=(25x2+−2x2)+(35xy+−35xy+8xy)+(−49y2+−8y2)
=23x2+8xy+−57y2
Plz mark brainlest :)

Answer: f(x) = (1/3)x + 3</h3>
This is basically in the form y = mx+b with m = 1/3 as the slope and b = 3 as the y intercept. I'm using f(x) in place of y to indicate function notation.
==========================================
Work Shown:
The goal is to solve for y.
x - 3y = -9
-3y = -9-x ... subtracting x from both sides
-3y = -x-9
y = (-x-9)/(-3) .... dividing both sides by -3
y = -x/(-3) - 9/(-3) ... break up the fraction
y = (1/3)x + 3 .... simplify
f(x) = (1/3)x + 3 .... replace y with f(x)
A & C, those are the numbers the only numbers that make the inequality true
