Of course! Just study hard, exams are a big part of your grade most of the time! I also have exams
Answer:
f(x)=x+2.
f(1/3x)=1/3 x+2=(x+6)/3or x/3+2
Answer:
f(x)=12x
Step-by-step explanation
We know that f(x) is our y-coordinate and x is the x-coordinate
Next we should insert x-6 as x in the equation
This is f(x)=12(x-6)-72
But if you look at this that leads to 12x-72 (ignore y-intercept)
That is our first equation
This means that if you take out -6 from the x
You will get f(x)=12x
(Also do you go to RSM?)
-4 (x - 5) + 3 (a - 7)
First, expand your problem. / Your problem should look like: -4x + 20 + 3a - 21
Second, simplify. / Your problem should look like: -4x + 3a - 1
Answer: -4x + 3a - 1 (C)
