a)if it rains today,then i will drive to work
b)if |x|=x then x>=0
c)if n is greater than 3,then n^2 is greater then 9

converse q then p
contrapositive not q then not p

converse q then p
contrapositive not q then not p
inverse not p then not q
i dont understand how to do b part
b) $$\displaystyle \text{If }|x|=x\text{ then }x\ge 0~.$$

Inverse: $$\displaystyle \text{If }|x|\ne x\text{ then }x< 0~.$$

Now you post the others.

converse if x>=0 then |x|=x
contrapositive if x ne 0 then |x| ne x

converse if x>=0 then |x|=x
contrapositive if x ne 0 then |x| ne x
NO!

$$\displaystyle \text{If }x<0\text{ then }|x|\ne x~.$$
