Janelle expanded the expression as shown below. -4(-3x + 2/7) = -12x - 3 5/7 what errors did she make? check all that apply.

a)the first term should be positive.

b)the second term should be positive.

c) she did not distribute the -4 properly.

d) she added 2/7 to -4 instead of multiplying 2/7 by -4

e) she did not simplify the expression completely.

A and D are true

Step-by-step explanation:

Julia had to expand the following expression:

Observing the correct method,

A)The first term should be positive.

As both -4 and -3x are negative, the first term should be positive.

B)The second term should be positive.

False.

C) She did not distribute the -4 properly.

False

D) She added 2/7 to -4 instead of multiplying 2/7 by -4

Yes because the multiplication gives 8/7

E) She did not simplify the expression completely.

False ..

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.

5x+10 is the correct one

hope this
