What is the value of f^-1(21)
elixir [45]

Given that f(x) = 2x + 11:  if f(x) = y = 21, then 21 = 2x + 11, and so 10=2x and x=5.

Thus, f(5) = 2(5) + 11 = 21; (5,21) is a point on the graph of f(x).

If that is so (which it is), then (21,5) is a point on the graph of the inverse function, and 5 is the appropriate output value.

Aretha is driving her car 325 miles to get to her vacation home. She travels the first 195 miles in 3 hours. At this rate, how l
mihalych1998 [28]

Answer:

For this case we know that the total distance to travel is 325 mi. And we know that Aretha travels at the following velocity:

V = \frac{X}{t} = \frac{195 mi}{3 hr}= 65 \frac{mi}{hr}

Then we can use the following definition:

D = Vt

Where D is the distance and V the velocity. And solving for t we got:

t = \frac{D}{V}

And replacing we got:

t = \frac{325 mi}{65 \frac{mi}{hr}}= 5

So then we can conclude that after 5 hours at this rate Aretha will arrive to home

Step-by-step explanation:

For this case we know that the total distance to travel is 325 mi. And we know that Aretha travels at the following velocity:

V = \frac{X}{t} = \frac{195 mi}{3 hr}= 65 \frac{mi}{hr}

Then we can use the following definition:

D = Vt

Where D is the distance and V the velocity. And solving for t we got:

t = \frac{D}{V}

And replacing we got:

t = \frac{325 mi}{65 \frac{mi}{hr}}= 5

So then we can conclude that after 5 hours at this rate Aretha will arrive to home
