You first substract 18 from both sides so you get
10x<-20 you then divide by 10 so the answer is
x<-2
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
and decline function would be
.
To find the time when both populations will be equal, we will equate both functions as:







Therefore, in 16 years the populations of the suburb and the city will be equal.
Answer:
Here, t represent <em>time</em>.
Step-by-step explanation:
we know that

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
<em>'t' Represent as ' Time'</em>

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 <u>discrete</u> set."
