Answer:
8-12n
Step-by-step explanation:
We can name "a number," "n."
4(2-3n)
Distribute.
4*2=8
4*-3n=-12n
8-12n
300 is the answer because it’s 600/2

Answer:
f^-1(x) is a function
Step-by-step explanation:
To get the inverse you replace f(x) with y, so you get y=3x^2+2. Then you switch your x and y to get x=3y^2+2. Now you want to solve for y, so you subtract two to get x-2=3y^2. You then divide both sides by 3 to get (x-2)/3=y^2. Finally you square root both sides to get y=√((x-2)/3). Now you get that f^-1(x)=√((x-2)/3). When you graph it you can see that the graph passes the vertical line test, so f^-1(x) is a function.
I believe the correct answer is 367.50
1,750×7%=122.50
122.50×3=367.50
Hope this helps
