Exercise 58 Page 552

Substitute -2 for a, and 3 for b.

0.75

Practice makes perfect

To evaluate the given expression for a = -2 and b = 3, we should substitute these values into the expression and simplify as much as possible. We are given an expression and asked to evaluate it for some given values. a=-2and b=3 This means that we should substitute -2 for a and 3 for b in the given expression and then evaluate. Let's start.

-b/2a

a= -2

-b/2* (-2)

b= 3

-3/2* (-2)

Multiply

-3/-4

- a/- b=a/b

3/4

Write as a decimal
