OpenStudy (anonymous):

Which expressions, when evaluated with y = –7, are positive in value? Choose all answers that are correct. A. 18 + 2y B. –3y + (–17) C. –2y – 23 D. –30 – 4y ill try

alones (alones):

This one is pretty tuff but still i'll explain so If you replace y with -7 you get: a. 18 +2x-7 b. -3x-7 + (-17) c. (-2x-7)-23 d. -30-4x-7 you get: a. 18-14 b. 21-17 c. 14-23 d. -30+28 this solves to: a. 4 b. 4 c. -9 d. -2 so the positive answers are a and b
