Plz me i’m so confused 23 points plz explain it to me in sooo stuck

6. D

7. B

Step-by-step explanation:

Nancy takes a test that has two sections: essay and true/false. She scores 56 points on the essay. Each true/false question is 4 points. So x number of true/false is worth 4 points each or 4x.

Together her score will be 56 + 4x.

She wants to score more than 80 or > 80.

So her test can be represented as the inequality 56 + 4x > 80.

This is solved using inverse operations.

56 + 4x > 80

4x > 24

x > 6

This should be graphed as an open circle at 6 on the umber line pointing and shaded to the the right for numbers greater than 6.

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.
