If f(x) = x2 – 2x and g(x) = 6x + 4, for which value of x does (f + g)(x) = 0?

 The required value of x is -2.

Step-by-step explanation:  We are given the expressions for two functions f(x) and g(x) as follows :

We are to find the values of x for which (f + g)(x) = 0.

We know that

for any two functions p(x) and q(x),

We have

Thus, the required value of x is -2.

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
