Question

Can some one help met with this? please!!!!!

Answer 1

1) a(-4) = -5 (-4) + 3

a(-4) = 20 + 3

a(-4) = 23

2) a(5) = -5 (5) + 3

a(5) = -25 + 3

a(5) = -22

3) b(-4) = 2 (-4) + 4

b(-4) = -8 + 4

b(-4) = -4

4) b(5) = 2 (5) + 4

b(5) = 10 + 4

b(5) = 14

5) 23 + (-4) = 19

6) -22 + 14 = -8

7) 23 - (-4) = 27

8) -22 - 14 = -36
