Exercise 36 Page P21

How can you isolate $r$ ?

${r ∣ r \geq 22}$

Practice makes perfect

Inequalities can be solved in the same way as equations, by performing inverse operations on both sides until the variable is isolated. The only difference is that when you divide or multiply by a negative number, you must reverse the inequality sign.

8 \leq r - 14

AddIneq

$LHS + 14 \leq RHS + 14$

22 \leq r

RearrangeIneq

Rearrange inequality

r \geq 22

This inequality tells us that all values greater than or equal to

22

will satisfy the inequality.
