Plzzz hurr its time
daniel expanded the expression as shown. what errors did he make? select three options.
-2(-8x-4y+3/4)=-10x-8y-1 1/4
a. the first term should be positive.
b. the second term should be positive.
c. the last term should be -1 1/2, not -1 1/4.
d. he divided -8 by -2 instead of multiplying -8 by -2.
e. he did not simplify the expression completely.

Daniel expanded the expression . The errors made by Daniel are

A. The first term should be positive.

B. The second term should be positive.

C. The last term should be -1 1/2, not -1 1/4.

Given :

Daniel expanded the expression as shown

Lets multiply -2 inside the parenthesis and see what happens

we know that negative times negative is positive

Also to simplify the fraction ,we can cancel out 2  and 4

So the first and second terms are positive

Also the constant term is -1 1/2

So the errors he make are

A. The first term should be positive.

B. The second term should be positive.

C.The last term should be -1 1/2, not -1 1/4.

Step-by-step explanation:

-2(-8x - 4y + 3/4) =

16x + 8y - 3/2 (-3/2 is the same as - 1 1/2)

errors

A. the first term should be positive

B. the second term should be positive

C. the last term should be - 1 1/2

answer: 4 (:

step-by-step explanation:

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
