Which value of x makes the open sentence true?
26−x2> 4x−20
8

7

6

5

First of all, it might be convenient to rewrite the inequality as

Then, we can plug the proposed value to see which one satisfies the inequality: we want the expression to evaluate to a negative value.

x=8:

x=7

x=6

x=5

So, the only value that returns a negative value is x = 5.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
