Question

Evaluate the expressions:

1. -8x when x=6

2. 3xsquared-5x when x=-2

3. -4((the absolute value sign) y-12 (the absolute value sign))when y=5

Answer 1

You can do these. Just substitute the indicated number value or y in the equation and do the computation.

For example, in #3, if y = 5, y-12 is -7 and the absolute value of that is +7. Multiply that by 4 for the answer.

Now you try the others. Show your work if you need further help.
