Select all of the expressions that are equivalent to 3x + 18

3(x + 6) and 4x + 18 - x

Step-by-step explanation:

Let's solve each option to see whether we would get 3x + 18:

✔️2x + 9 + 2x + 9

Add like terms

2x + 2x + 9 + 9

4x + 18

✔️3(x + 6)

3*x + 3*6

3x + 18 (it is an equivalent)

✔️4x + 18 - x

Add like terms

4x - x + 18

3x + 18 (it is an equivalent)

✔️2(4x + 9)

8x + 18

Therefore, the expressions 3(x + 6) and 4x + 18 - x are equivalent to 3x + 18

step-by-step explanation:

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
