I think so because she started at 2 1/4 then hiked to 4 3/8. That is roughly 2 miles and then from there she joked all the way back to 11/2
Hello from MrBillDoesMath!
Answer:
x = 30
Discussion:
Note: I ignored the * in f*(x) as i don't know what it means. (If this is not what you intended, please indicate what * means)
f(x) = 2 sqrt(x-5) + 4
f(x) = 14
=>
14 = 2 sqrt(x-5) + 4 => subtract 4 from both sides
14 -4 = 2 sqrt(x-5) => divide both sides by 2
10/2 = sqrt(x-5) =>
5 = sqrt(x-5) => square both sides
5*5 = x-5 => add 5 to both sides
5*5 + 5 = x
25 + 5 = x
x = 30
Thank you,

Answer:
F-1(x)=7/(x+9)
Step-by-step explanation:
Change F(x) to y so y=7/x -9
Swap variables x=7/y -9
Solve x+9=7/y
7/(x+9)=y
Then change y to F inverse
F-1(x)=7/(x+9)
Thats ur inverse!!!
Answer:
there are no real solutions
Step-by-step explanation:
there is a rule that says
so we have
and we have the definition
so we have
and using the quadratic formula we get that
there are no real solutions
