475 = 75x + 100

solve:

75x = 375

Rudiy27

Answer:

x^2 - 2x - 1.

Step-by-step explanation:

(g - f)(x)

= g(x) - f(x)

= x^2 - 2 - (2x - 1) (Note we put the 2x -1 in parentheses).

= x^2 - 2 - 2x + 1

= x^2 - 2x - 1.

Solve the formula Ax+Bx = c for y

IgorC [24]

Answer:

Step-by-step explanation:

The correct formula given is:

$Ax+By=c$

We need to solve for y. First, we isolate the "y" term:

$Ax+By=c\\By=c-Ax$

Now, there's a "B" with y, to isolate the "y", we need to divide both sides by "B" and get "y":

$By=c-Ax\\\frac{By}{B}=\frac{c-Ax}{B}\\y=\frac{c-Ax}{B}$

Answer choice B is right.
