Question

Which inequality is equivalent to -r >13?

Answer 1

Hey there!

-r > 13

-1r > 13

DIVIDE -1 to BOTH SIDES

-1r/-1 > 13/-1

CANCEL out: -1/-1 because it gives you 1

KEEP: 13/-1 because it help solve for the r-value

NEW EQUATION: r > 13/-1

SIMPLIFY IT!

r < -13

It is an OPEN circle shaded to the LEFT

Therefore, your answer is: r < -13

Good luck on your assignment & enjoy your day!

Answer 2

`r \: < \: - 13`

Explanation:

The given inequality is

`- r \: > \: 13`

We need to simplify this inequality.

We multiply both sides by -1 and reverse the inequality sign.

This implies that:

`r \: < \: - 13`

This can also be written as:

`- 13 \: > r`

All these are equivalent to the given inequality.
