Answer:

5) x = 77

7) b = 210

Step-by-step explanation:

5) 11 = X/7

multiply both sides by 7. doing this gets rid of the 7 on the right side of the equation.

(7)(11) = x

77 = x

7) 14 = b/15

same thing as above! multiply both sides by 15.

(15)(14) = b

210 = b

Hope this helps you!

2) f(x) = x² ** g(x)= 3x – 2 Find f(g(-4)

Usimov [2.4K]

Answer:

$f(g( - 4)) = 196$

Step-by-step explanation:

The functions are;

$f(x) = {x}^{2}$

and

$g(x) = 3x - 2$

We want to find

$f(g( - 4))$

First we find g(-4) to get:

$g( - 4) = 3 \times - 4 - 2$

$g( - 4) = - 12- 2$

$g( - 4) = - 14$

Now

$f(g( - 4)) = f( - 14)$

This implies that,

$f(g( - 4)) = {( - 14)}^{2}$

$f(g( - 4)) = {( - 14)} \times - 14$

$f(g( - 4)) = 196$

__ x 5 > 5 3/3 2/3 5/3

Citrus2011 [14]

_ * 5 > 5

3/3 is equal to 1 which would make them equal to each other.
2/3 is less than one which means it would make the number on the left less than 5, not greater than.
the answer is 5/3 because it is bigger than the other answer choices and will result in a greater number than that on the right.
