The steps below show the incomplete solution to find the value of x for the equation 7x – 3x – 4 = –1 + 21:

step 1: 7x – 3x – 4 = –1 + 21

step 2: 7x – 3x – 4 = 20

step 3: 4x – 4 = 20which of these is most likely the next step? (4 points)

4x = 24
4x = 16
4x = 5
4x = 80

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

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.
