Answer:

  3x minutes

Step-by-step explanation:

Kimberly desperately needs a more fuel-efficient vehicle. Her usage rate is ...

  (50 mi/h)(200 gal)/(500 mi) = 20 gal/h = 20 gal/(60 min) = 1/3 gal/min

Using gasoline at the rate of 1/3 gal/min, her time for x gallons is ...

  (x gal)/(1/3 gal/min) = 3x min

It will take 3x minutes for Kimberly to use x gallons at the same rate.

The population of a town was 5655 in 2010. The population grows at a rate of 2.6% annually.
kupik [55]

The exponential equation used to represent the population of the town is given by y = 5655(1.026)ˣ

An exponential function is in the form:

y = abˣ

where y, x are variables, a is the initial value of y and b is the multiplier.

Let y represent the population remaining after x years.

The population grow at the rate of 2.6% annually. Hence:

b = 100% + 2.6% = 1.026

There are initially 5655 people, hence a = 5655.

The equation becomes:

y = 5655(1.026)ˣ

Is 2x+3x=4 a function or not a function?
Crank

Answer:

f(x) = 3x2 + 5 and y = 3x2 + 5

Step-by-step explanation:

The expressions that follow f(x) = and y = are the same, so these are two different ways to write the same function: f(x) = 3x2 + 5 and y = 3x2 + 5.
