-w + 4(w + 3) = -12
expand (4 × w, 4 × 3)
-w + 4w + 12 = -12
3w + 12 = -12
- 12
3w = -24
÷ 3
w = -8

I hope this helps!

Let g (x) = 3x+2 and f (x) = x-2 / 3 find the value. g (f(2))

Romashka [77]

Answer: OPTION C.

Step-by-step explanation:

In order to solve the given exercise, you can follow these steps:

1. Given the following function f(x):

$f(x)=\frac{x-2}{3}$

You must substitute $x=2$ into the function f(x). Then:

$f(2)=\frac{(2)-2}{3}$

2. Evaluating, you get:

$f(2)=\frac{0}{3}\\\\f(2)=0$

3. Now, the next step is to substitute $f(2)$ into the function g(x):

$g (x) = 3x+2\\\\g (f(2)) = 3(0)+2$

4. Finally, evaluating, you get the following result:

$g (f(2)) = 0+2\\\\g (f(2)) =2$

You can identify that it matches with the Option C.

Which object has the same y-intercept as a function y=2/3x-3?

Licemer1 [7]

The 4th option.

The values with no x or y attached are the y intercept

6x - 7y = 21

Subtract 6x from both sides

6x - 7y - 6x = 21 - 6x

-7y = 21 - 6x

Divide both sides by - 7

-7y/-7 = 21/-7 - 6x/-7

Y = -3 +6x/7

The why intercept, -3 is the same as the one in the question
