Question

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

Answer 1

Answer:

x > 9

Step-by-step explanation:

Hello!

First let's solve the inequality for x.

Flip the sign if you are dividing by a negative number.

Solve for x

• $-3x - 7 < 20$
• $-3x < 27$
• $x > 9$

Now let's graph it on a number line. If it is a greater or less than symbol, we use an open circle. If it is a greater than or equal to or a less than or equal to, we use a closed circle.

Plot the point of 9 with an open circle, and shade in a line towards the right (all values greater than 9).
