Answer: f(2)=156
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have the following function:

2. Then, you must substitute x=2 into the function given in the exercise. Therefore, you have the following result:

Answer:
m = 3
Step-by-step explanation:
-3m - 6 = 6 - 7m
-3m + 7m = 6 + 6
4m = 12
m = 12/4
m = 3
Answer:
y=1/3x + 2
Step-by-step explanation:
Since slope intercept form is y=, I first added x to each side to get x on the other side. Then I divided each side by 3 to get y, and ended up with y=1/3x+2 as my answer.
