If f(x) = x^2 + 2x - 4 and g(x) = - 4x +1, what is (g-f)(x)?

Work Shown:

(g - f)(x) = g(x) - f(x)

(g - f)(x) = (-4x+1) - (x^2+2x-4)

(g - f)(x) = -4x+1 - x^2-2x+4

(g - f)(x) = -x^2+(-4x-2x)+(1+4)

(g - f)(x) = -x^2 - 6x + 5

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

i think the amount would be $140.62
