Y= -x-2; (2,4) a solution not a solution show me step by step

not a solution

Step-by-step explanation:

Y= -x-2;(2,4)

4= -2-2

4=-4

The ordered pair is not a solution doesn't equal

where's the diagrams?

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.
