Steps to finding the inverse:
1. Replace f(x) with y.
2. Swap x and y.
3. Solve the equation for y.
f(x) = 2x - 10
1. y = 2x - 10
2. x = 2y - 10
3. Add 10 to both sides
x + 10 = 2y
Divide both sides by 2
(x + 10)/2 = y
y = (x + 10)/2
f^-1(x) = (x + 10)/2
Answer:
C) 2.5
Step-by-step explanation:
8.8=x*3.5
divide 3.5 on both sides.
Answer:
-6
Step-by-step explanation:
The answer is 56! I used a double number line! You have to get the unit rate first! Unit means 1, you have to get from 12 to 1! I did 12 divided by 12, and got 1! Whatever I do to the bottom I do to the top. So I divided 60 by 12 and got 5. Now we have to get to seven, so I multiplied 1 x 7 and got 7. Than I multiplied 5 times 7 and got 56! I hope <em>I helped! :D</em>
