PLEASE HELP! Let f(x)= 6x+1 find f(a) + f(2)

SpyIntel [72]

Answer:

6(a)+14

Step-by-step explanation:

First you need to find f(a) and f(2) separately, then add them together after

f(a) = 6(a)+1

f(2) = 6(2)+1 = 12+1 = 13

so f(a)+f(2) = 6(a)+1+13 = 6(a)+14

Which of the following equations shows how substitution can be used to solve

maxonik [38]

Answer: Choice B)

2x+5(2x+3) = 3

============================================

Reasoning:

We start with the second equation 2x+5y = 3

Since y = 2x+3 from the first equation, we can replace every copy of y with (2x+3). This replacement is valid because y and 2x+3 are the same.

So that's how we go from 2x+5y = 3 to 2x+5(2x+3) = 3

This replacement is done to get rid of the y variable, and it allows us to solve for x later on.
