Which expressions, when evaluated with z = 8, are negative in value?Choose all answers that are correct.

A.

–2z – 14

B.

–25 + 4z

C.

–2z + 15

D.

30 – 3z

Answers

$z=8\n\nput\ the\ value\ of\$

To find out which equation is negative when you plug in z=8, then plug it in and find out! :D

A) –2z – 14 = -2(8)-14 = -16-14 = -30

-2x-14 is negative when z = 8. So A is one possible answer :)

B) –25 + 4z = -25 + 4(8) = -25 + 32 = 7

7 is positive when z = 8, so B is not a correct answer.

C) –2z + 15 = -2(8) + 15 = -16 + 15 = -1

-1 is negative when z 8, So C is another correct answer choice.

D) 30 – 3z = 30 - 3(8) = 30 - 24 = 6

6 is positive when z=8, So D is not a correct answer.

To summarize, your answer would be A and C.
