Answer:
$80.73
Step-by-step explanation:
115 * 0.35 = $40.25 off
115 - 40.25 = $74.75 after sale
add tax (0.08)
74.75 * 0.08 = $5.98 tax
74.75 + 5.98 = $80.73 in total
-2 is the answer when i figured out the problem
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.
First arrange them in ascending order.
