Answer:

<u>Divide by -8</u> on both sides. <u>Flip</u> the inequality.

Step-by-step explanation:

You didn't provide any answer choices, but here's how you would solve this:

$-8x < 32\\\\\frac{-8x}{-8} < \frac{32}{-8}\\ \\x > -4$

Notice that because we divided by a negative, the inequality sign must flip in the other direction!

Answer: x<5

Step-by-step explanation:

If the circle was dark then it would be x is less than or equal to 5. But here, since the circle is open, that means that 5 is not a possible solution for x. The answer is x<5. Hope this helps!

Then you square root 25 which is 5 so
c is 5
