Kahirap naman nyan
Step-by-step explanation:
Sorry
F⁻¹(x) is the notation for the inverse of an equation, so you just need to find the inverse equation. that's found by swapping your x and y variables:
<span>f(x) = 2x + 2 ... replace f(x) with y
y = 2x + 2 ... swap x and y variables
x = 2y + 2 ... solve for y
x = 2y + 2 ... subtract 2
x - 2 = 2y ... divide by 2
(x - 2)/2 = y
so, </span>f⁻¹(x) = (x - 2)/2 ... now you need to solve that for when x = 4. plug it in:
f⁻¹(x) = (4 - 2)/2 ... simplify the top of the fraction
f⁻¹(x) = 2/2
f⁻¹(x) = 1 is your answer.
1/4
if 3/4 cyclists finish then that leaves 1/4 of the group that did not finish

Answer:
54.72
Step-by-step explanation:
- multiply 19% by 0.01
- multiply 0.19 by 288
19·0.01=0.19
0.19·288=54.72
Therefore, 19% of 288 will be 54.72.
