To find the inverse, interchange the variables and solve for y. You should get
f^-1 (x)= -56/5 + 7x/5
Answer:
Hello! The median is 82 and 100.
Step-by-step explanation:
The median is just the number or numbers in the middle! Hope this helps!
1) Divide both sides by 2
2x+12^2/3 =16
2) Solve the exponent
2x+12^2/3 =16
(2x+12^2/) ^3/2 =16^3/2 ( raise both sides to power)
2x+12 = 64
3) Subtract 12 from both sides
2x + 12 - 12 = 64-12
2x = 52
4) divide both sides by 2
2x/2 = 52/2
x = 26
Final answer : x = 26
The negative sign in the multiplication calculation can be moved to everywhere. So the number should be -8.
