Exercise 34 Page 174

Substitute - 2 into the given inequality and then simplify.

Yes, see solution.

Practice makes perfect

We can determine whether p= - 2 is a solution by substituting it into the inequality and simplifying using the order of operations.

7p≥ p-12
Substitute

p= - 2

7( - 2) ? ≥ - 2-12
MultPosNeg

a(- b)=- a * b

-7( 2) ? ≥ - 2-12
Multiply

Multiply

- 14 ? ≥ - 2-12
SubTerm

Subtract term

- 14 ≥ - 14 ✓

Since - 14 is greater than or equal to - 14, this means that p= - 2 is a solution.
