The population of people in a town increases by 100 each year. Which equation represents the situation? Let p represent the amount the population has increased and t represent the number of years.t = 100 + pp = 100 + tt = 100pp = 100t
Answers
From the problem, the population increases by 100 each year.
a constant increase of 100 means that the slope of a line is 100.
Slope is the same as constant increase or rate of increase.
The equation of the line with a slope is :
[tex]y=mx+b[/tex]where m is the slope and b is the initital population.
Since we dont have an initital population, b = 0.
The equation will be :
[tex]y=100x[/tex]It is stated also that P represents the population that has increased. So y will be p.
and t represent the number of years. So x will be t.
That will be :
[tex]p=100t[/tex]ANSWER :
The equation is p = 100t

Of all the people going, 5/8 are children and 3/8 are adults. How much moreis 5/8 than 3/8?Explain your answer using equations, diagrams, and words.
Answers
Given, the fraction of children, C=5/8.
The fraction of adults, A=3/8.
Therefore 5/8 is more than 3/8 is given by,
[tex]\begin{gathered} \text{Percent}=\frac{C-A}{A}\times100 \\ =\frac{\frac{5}{8}-\frac{3}{8}}{\frac{3}{8}}\times100 \\ =\frac{\frac{5-3}{8}}{\frac{3}{8}}\times100 \\ =\frac{2}{3}\times100 \\ =66.67 \end{gathered}[/tex]Therefore, 5/8 is more than 3/8 by 66.67%.
In each of the figures, there are 8 boxes. In the first figure showing the fraction of children, two boxes are shaded more than the figure for adults. In the second figure for the fraction of adults, only 3 boxed are shaded.
So, the % by which 5/8 is more than 3/8 can be found as
[tex]\begin{gathered} \text{percentage}=\frac{Number\text{ of extra shaded boxes in first figure}}{\text{Number of shaded boxes in second figure}}\times100 \\ =\frac{2}{3}\times100=66.67 \end{gathered}[/tex]5/8 is 5 parts of 8. 3/8 is 3 parts of 8. So, if the total number of people is 8, five people are children and three people are adults.
So, number of children is 2 more than the number of adults, whose number is 3.
Therefore, the fraction for number of children more than the adults with respect to the number of adults is 2/3. In percentage,
[tex]\text{percentage}=\frac{2}{3}\times100=66.67[/tex]So, 5/8 is more than 3/8 by 66.67%.
9) Write the slope-intercept form of an equation for
the line of fit. Use points (15, 40) and (41, 61).
Answers
The linear equation that passes through (15, 40) and (41, 61) is:
y = (21/26)*x + 725/26
How to get the linear equation?A general line is written as:
y = m*x + c
Where m is the slope and c is the intercept of the y-axis.
If the linear equation passes through two points (x₁, y₁) and (x₂, y₂), then the slope can be written as:
slope = (y₂ - y₁)/(x₂ - x₁)
In this case the line passes through (15, 40) and (41, 61), then the slope is:
m = (61 - 40)/(41 - 15) = 21/26
Then the line is:
y = (21/26)*x + c
To find the value of c we can replace the values of one of the poitns, if we use the first one we will get:
40 = (21/26)*15 + c
40 = 315/26 + c
40 - 315/26
725/26 = c
The linear equation is.
y = (21/26)*x + 725/26

Use graphs to find the set.(−2,4) ∪ [−1,6]Im not for sure on how to solve the set?
Answers
Answer:
A. The set is {-1, 0, 1, 2, 3, 4, 5, 6}
Explanation:
Note the following;
*When we use parentheses or open brackets, ( ), in an interval notation, it signifies that those points are excluded in the set.
*When we use closed or square brackets, [ ], in an interval notation, it signifies that those points are inclusive in the set.
*The union symbol (U) is used to join two intervals together.
Given the interval notation, (−2,4) ∪ [−1,6], since there -2 and 4 are in parentheses, it means that they are not included in the set while -1 and 6 are included in the set since they are in square brackets. So the members of the set can be represented in a graph as;

The compound interest model is given by the following expression:
[tex]y=a(1+\frac{r}{n})^{nx}[/tex]Where a is the principal (initial amount), r is the interest rate in decimal form, n is the number of times compounded in a year and x is the number of years.
a) In this case, $4 are invested at 1% interest rate, then a = 4, r = 0.01 (1%) and n = 4 (compounded quarterly) and the above equation can be rewritten to get a model that led us to calculate the value of your shares over the time like this:
[tex]y=4(1+\frac{0.01}{4})^{4x}[/tex]b) By replacing 0 for x, we can determine the y-intercept of the model, like this:
[tex]y=4(1+\frac{0.01}{4})^{4(0)}=4(1+\frac{0.01}{4})^0[/tex]The result of raising any number to 0 is 1, then we get:
[tex]y=4(1+\frac{0.01}{4})^0=4(1)=4[/tex]Then, the y-intercept if this model is 4 and it represents the initial amount invested ($4)
c) By replacing 10 for x, we get:
[tex]y=4(1+\frac{0.01}{4})^{4(10)}=4(1+\frac{0.01}{4})^{40}=4.42[/tex]Then, after 10 years the estimated value of the shares will be $4.42
d) for a $4 stock with 2% interest compounded semiannually the model changes, we can write it like this:
[tex]y=4(1+\frac{0.02}{2})^{2x}[/tex]By replacing 10 for x, we get:
[tex]y=4(1+\frac{0.02}{2})^{2(10)}=4.88[/tex]As you can see, after 10 years the estimated value of the shares will be $4.88, which is greater than the previous penny stock investment, you would have shared better.

Answers
Step-by-step explanation + Answer:
x = 1st job
y = 2nd job
x + y = 22......x = 22 - y
7x + 8.25y = 171.50
7(22 - y ) + 8.25y = 171.50
154 - 7y + 8.25y = 171.50
-7y + 8.25y = 171.50 - 154
1.25y = 17.50
y = 17.50 / 1.25
y = 14 <== 14 hrs at the 8.25 per hr job
x + y = 22
x + 14 = 22
x = 22 - 14
x = 8 <=== 8 hrs at the 7 per hr job

342 peanuts were divided equally into 6 small bags. "p" represents the total number of peanuts
To determine how many peanuts go in each bag, you have to divide the total amount of peanuts by the number of bags:
[tex]\frac{p}{nº\text{bags}}=\frac{342}{6}=57[/tex]The variable of this example is the number of peanuts, and the constant is the number of bags.
So, the statements that apply are:

- 342 divided by 6 equals 57
-Each bag will have 57 peanuts.
-To evaluate, substitute 342 for the variable.
-Write the division expression as a fraction,
