3(x+4)=-18 Please go step by step!

x=-2

Step-by-step explanation:

3x+12=-18

+12

3x=-6/3

hi

Step-by-step explanation:

3(x+4)=-18

3 × X + 3× 4=-18

3x+12=-18

3x=-18-12

3x= -30

x= -30/3

x= -10

hope it helps

have a nice day

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

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.
