Answer:
x=-4
Step-by-step explanation:
Just had it on a test and got it write
An inverse function reverses the roles of inputs and outputs (of x-values and y-values).
If (2,4) is on the graph of a function, then (4,2) is on the graph of the inverse function.
If (9,7) is on the graph of the inverse, then (7,9) would be on the graph of the original function.
If (a,b) is on the graph of the function, then (b,a) is on the graph of the inverse.
Getting to your question, which of the points listed has the inverse listed up in the table?
Answer:
Step-by-step explanation:
d≈12ft
A Area

r
d
d
C
A
Using the formulas
A=πr2
d=2r
Solving ford
d=2A
π=2·113.04
π≈11.99696ft
There are 65 boys, and the boy ratio is 13: so to find how they got that, divide 65 by 13 and that is 5. Since we now know it is the amount of people, divided by 5, we can take the girl ratio (15) and multiply it by 5 to get the amount of girls (which is 75). You need to find the total amount of students in the class so add the boys and girls (65+75) and get 140 total students
