Can some one help met with this? please!!!!!
1 answer:
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
