If g(x) = 3x + 2 and f(x) = 5x - 4, what is f(g(x)) ?

you set them = to each other

3x+2= 5x-4 (subtract 5x from both sides)

-2x +2 = -4 (subtract 2 from both sides)

-2x = -6 (divide by -2)

x = 3 (your answer)

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
