First replace y with 15.
1/5x-10=30
Then just solve from there.
x=200
You multiply by 10 or more
Answer:
Option A
Step-by-step explanation:
Domain should be greater than/equal to 1 for the function to be one-one.
f has vertex at (1,0)
f inverse has (0,1)
f(x) = 4
(x - 1)⁴ = 4
x = 2.414
On f: (2.414, 4)
On f inverse: (4, 2.414)
In Y=mx+b:
m=slope. That is found by using this formula y2-y1/x2-x1
b=y-intercept. That's found by finding slope, m, and substituting that into y=(m)x+b. Then you have to solve for b and that'll be your y-intercept.
