ANSWER

EXPLANATION
The given inequality is,

By the definition of absolute value,

We divide through by negative 1, in the first part of the inequality and reverse the sign to get,

We simplify now to get,


Divide through by 2 to obtain,
Replace the x in 7x by (3x + 1):-
(f o g)(x) = 7 * (3x + 1)
= 21x + 7 which is choice D.
11, because 11 times 1 is 11 and 11 times 4 is 44.
<h2>
Answer:</h2>
Since both angles are vertical angles, we need to set them equal to each other.

The final answer is <em>x = 10</em>.
