Rework problem 15 in section 2 of Chapter 5 of your textbook about the growing suburb and the declining city using the following

bazaltina [42]

Answer:

16 years.

Step-by-step explanation:

Please consider the complete question.

Assume that the suburb has a population of 686,000 and is growing at a rate of 4000 per year. Assume that the city has a population of 942,000 and is declining at a rate of 12000 per year. In how many years will the populations of the suburb and the city be equal?

Let x represent number of years.

Growth function would be $G(x)=4000x+686,000$ and decline function would be $D(x)=942,000-12,000x$ .

To find the time when both populations will be equal, we will equate both functions as:

$4000x+686,000=942,000-12,000x$

$4000x+12,000x+686,000=942,000$

$16,000x+686,000=942,000$

$16,000x=942,000-686,000$

$16,000x=256,000$

$\frac{16,000x}{16,000}=\frac{256,000}{16,000}$

$x=16$

Therefore, in 16 years the populations of the suburb and the city will be equal.

you ride your bike at 9 miles per hour. To find how long it will take you to ride 26 miles, you solve the equation 9 • t = 26. W

Vikentia [17]

Answer:

Here, t represent time.

Step-by-step explanation:

we know that

$speed = \frac{distance}{time}$

Given that speed = 9 miles per hour

Distance travelled = 26 miles

Therefore, Distance = Time x Speed.

Putting value into calculation.

26 = 9 x Time

By comparing equation. we can say that

't' Represent as ' Time'

Is the answer option c?

Masja [62]

Answer:

Discrete

Step-by-step explanation:

A set can simply be defined as a list of values. There are many different types of sets, some are intervals, others are enumerated numbers. Often, a set composed of values that are listed is referred to as a discrete set. Discrete sets can be a list of information, or "isolated points". Knowing this information, the most logical answer to fill in the blank is "discrete".

"If a set is made up of isolated points and can be written as a list, it is called a discrete set."
