<h3>
Answer: -10</h3>
=================================================
Work Shown:
First we need to evaluate f(3)
f(x) = -x^2 + 2x
f(x) = -(x)^2 + 2(x)
f(3) = -(3)^2 + 2(3) ... replace every x with 3; apply PEMDAS to simplify
f(3) = -9 + 6
f(3) = -3
Then we subtract 7 from both sides
f(3) - 7 = -3 - 7
f(3) - 7 = -10
De hecho, no tengo idea de cuál es la respuesta, solo estoy tratando de obtener puntos. ahora diré algunos números aleatorios 125 y 555 multiplicados divididos en la desigualdad. espero que tengas un gran día si puedes leer esto, dios los bendiga ♥ ️

Tell me if you need the step-by-step explanation
I don’t now good luck!!!!!!!!!!!!!!!!
It must have the same slope as the given line, so
m = -A/B = -1/-2 = 1/2
So far, we have
y = mx + b = x/2 + b
Use the given point to find b.
4 = -2/2 + b = -1 + b
b = 5
y = x/2 + 5
Multiply through by 2.
2y = x + 10
Standard form:
x - 2y = -10
