Hey there!
Your equation will be f(x) = (5x + 1) / 2. Now, you'll need to find the inverse.
In the equation, replace f(x) with y, then switch x and y. Now, solve for y in the new equation. What equals y will be your inverse equation.
f(x) = (5x + 1) / 2
x = (5y + 1) / 2
(x)*2 = (5y + 1 / 2)*2
2x = 5y + 1
–1 –1
(2x – 1) / 5 = (5y) / 5
(2x – 1) / 5 = y
Your inverse function is f–1(x) = (2x – 1) / 5. Now, just plug in 8 for x and solve for the answer.
f–1(x) = (2x – 1) / 5
f–1(8) = (2(8) – 1) / 5
f–1(8) = (16 – 1) / 5
f–1(8) = 15 / 5
f–1(8) = 3
Your final answer will be 3. Hope this helped you out! :-)
Answer:
-3y + -9/2
Step-by-step explanation:
Leg 1 is 13 - 1 (which is 12)
Leg 2 is 9 - 4 (which is 5)
We can use the Pythagorean theorem to solve for the distance (hypotenuse):
12^2 + 5^2 = c^2
144 + 25 = c^2
169 = c^2
c =
c = 13
The distance is 13 units.

Evaluating a function means substituting the variable (x in this case) by the given value (4 in this case), so where is an "x" we should rewrite with the number 4.
So, evaluating the function for we have:
