Question

Which graph shows the solution to the inequality -3x-7 <20?

Answer 1

Graphs..?

Explanation:

Answer 2

For this case we must indicate the graph of the following inequality:

`-3x-7 <20`

We add 7 to both sides of the inequality:

`-3x <20 + 7\\-3x <27`

We divide between -3 to both of the inequality taking into account that the meaning changes:

`x> \frac {27} {- 3}\\x> -9`

Answer:

`x> -9`
