Answer 2

To evaluate the expressions, let's substitute the given values for the variables and perform the calculations.

1. For the expression 0.4y + 1:

a) When y = -0.5: 0.4(-0.5) + 1 = -0.2 + 1 = 0.8

b) When y = 8: 0.4(8) + 1 = 3.2 + 1 = 4.2

c) When y = -10: 0.4(-10) + 1 = -4 + 1 = -3

2. For the expression 2.7c - 0.2d:

a) When c = -28 and d = 15: 2.7(-28) - 0.2(15) = -75.6 - 3 = -78.6

Therefore: a) When y = -0.5: 0.4y + 1 = 0.8 b) When y = 8: 0.4y + 1 = 4.2 c) When y = -10: 0.4y + 1 = -3

2. When c = -28 and d = 15: 2.7c - 0.2d = -78.6
