Given f (x) = 3x – 5 and g(x) = 2x + 1, find g(f(x)). 6x2 – 7x – 5 6x – 10 6x – 2 6x – 9
N76 [4]

Answer:

g(f(x)) = 6x - 9

Step-by-step explanation:

To find g(f(x)), substitute x = f(x) into g(x) , that is

g(3x - 5)

= 2(3x - 5) + 1 ← distribute parenthesis and simplify

= 6x - 10 + 1

= 6x - 9

A machine can reshape the body of a flattened can to a round shape. The machine can reshape 75 cans in 5 minutes. At what rate p
nignag [31]
The answer is 15 cans per minute. Here is how I did it: I know that you need to find how many cans per minute so I divided 5 by itself to get one because you are finding out how many cans per one minute then I did the same to 75 because when doing this type of problem you have to divide the first number which in this case is 75 by the second number which in this case is 5. And when I divided 75 by 5 I got fifteen so 15 cans per minute is the answer. Hope I helped!
