F(x) = 3x; g(x) = 5x+2 What is f(x) - g(x)?

-2x - 2

Given:

f(x) = 3x , g(x) = 5x + 2

Step-by-step explanation:

f(x) - g(x)

⇒ 3x - (5x + 2) [remember: (-)(+) is (-) ]

⇒ 3x - 5x - 2

⇒ -2x - 2

hope you understood!

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.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
