Answer:

1. 11  

2. 4

3. 8

4. 36

Solution:

1. Evaluate: -3x + 5 for x= -2.

-3x + 5

-3(-2) + 5

6 + 5

= 11

 

2. Evaluate 2x + 6y - 3 for x = 5 and y=-1/2

2x + 6y - 3

2(5) + 6(-1/2) - 3

10 - 3 - 3

=4

3. Evaluate x3 - 7 when x=5

x3 - 7

(5)3 - 7

15 - 7

=8

4. 4a + a/c when a = 8 and c = 2​

4a + a/c

4(8) + (8)/(2)

32 + 4

= 36
