In a recent survey, a magazin reported that the recommended room temperature in the summer is 68°F. Colby notices that his bedroom's temperature is 6 °F below the recommended temperature and the living room is 6 °F above the recommended temperature. He graphs 74 and 62
on a number line and determines they are opposites. Is Colby correct? Explain.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

step-by-step explanation:

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.
