Answer:
An absolute number is a number that is represents a distance from 0. An absolute number is always positive since the distance between two number is always positive.
Step-by-step explanation:
Find the distance between the following pair of points.
A(-3,1), B(7,13)
Answer:
15.6 units (3 s.f.)
Step-by-step explanation:
The distance between 2 points is given by the formula below, where [tex](x_1, y_1)[/tex] is the first coordinate and [tex](x_2, y_2)[/tex] is the second coordinate.
[tex]\boxed{{\text{Distance between 2 points}= \sqrt{(y_1 - y_2)^{2} + (x_1 - x_2)^{2} } }}[/tex]
Using the distance formula above,
distance between A(-3, 1) and B(7, 13)
= [tex]\sqrt{(13-1)^{2} + [7-(-3)]^{2} } }}[/tex]
= [tex]\sqrt{12^2+(7+3)^2}[/tex]
= [tex]\sqrt{244}[/tex]
= 15.6 units (3 s.f.)

John and Joan shared an amount of money in a ratio 5:7. Joan had $45 more than John - find the amount each received
John received $112.5 and Joan received $157.5 respectively as per the given ratio.
John and Joan share the amount in the ratio: 5:7
it is given that Joan had $45 more amount than John, therefore
Let the amount with John be x, so the amount with Joan will be x + 45
Formulating the equation we get:
Amount with John/Amount with Joan = Ratio of money with John/Ratio of money with Joan
x/(x + 45) = 5/7
7x = 5x + 225
2x = 225
x = 112.5
Amount with John = 112.5
Amount with Joan = 157.5
So, amount John received $112.5 and Joan received $157.5 respectively.

Answer:
y=3x-8
Step-by-step explanation:
Slope -intercept form is y=mx+b.
M represents the slope; b represents the y-intercept.
First, let's find the y-intercept.
It'll be found on the y-axis on the graph.
If you go down the y-axis, you'll see that -8 is the only point to be directly on the y-axis, so we can assume that that's the y-intercept.
Thus, the B in the equation is -8.
Now, let's find the slope.
You can think of it as rise over run. The rise is how many numbers the y-intercept either goes up or down until it can cross over to the x-axis. Crossing sideways is the run that's located on the x-axis.
You can begin from -8 and either count downward or upward.
For the sake of this graph, we'll go upward.
Do you see the dot on the coordinate (1,-5)?
Count upward and go to the side to get to that coordinate.
I count three upward and one to the right.
So as a fraction that would be 3 over 1 or 3/1.
But you can simplify that to just 3.
Thus, the M in the equation is 3.
Hence, y=3x-8.
Hope this helps.

The enrollment of a community college last
year was 4500 students. It increased by 5%
this year. What is the enrollment this year at
the community college?
Answer:
4725 Students
Step-by-step explanation:
First, multiply 4500 by 0.05 (which is 5% in decimal format.) You should get 225. Next, add 225 to the original value of 4500; you should get the answer, which is 4725 :)
Answer:
4725 Students
Step-by-step explanation:
To find the total enrollment of the community college this year, all we have to do is add the previous year's enrollment to 5% of the same value.
So...
Previous enrollment: 4500
5% of Previous enrollment = 0.05 * 4500 = 225
This year's enrollment = 4500 + 225 = 4725
So the final answer is 4725 students.

Answer:
(a) 3.5
(b) x = 4
(c) -¹/₂
(d) -¹/₂
Step-by-step explanation:
Part (a)f(1) is the value of y when x = 1.
To find the value of y from a given value of x, find the position of x on the x-axis, then trace vertically until you meet the line. Once you meet the line, trace horizontally to the y-axis to find the corresponding value of y.
Therefore, f(1) = 3.5.
Part (b)To solve f(x) = 2, find the value of x when y = 2.
To find the value of x from a given value of y, find the position of y on the y-axis, then trace horizontally until you meet the line. Once you meet the line, trace vertically to the x-axis to find the corresponding value of x.
Therefore, the solution of f(x) = 2 is x = 4.
Part (c)The average rate of change of function f(x) over the interval a ≤ x ≤ b is given by:
[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]
Given interval: 2 ≤ x ≤ 4
Therefore:
a = 2b = 4[tex]\implies \dfrac{f(4)-f(2)}{4-2}=\dfrac{2-3}{4-2}=-\dfrac{1}{2}[/tex]
Part (d)The average rate of change between any interval of the given function will be the same as the graph is linear. Therefore, the average rate of change from 0 to 8 is the same as the rate found in part (c): -¹/₂.
Proof
The average rate of change of function f(x) over the interval a ≤ x ≤ b is given by:
[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]
Given interval: 0 ≤ x ≤ 8
Therefore:
a = 0b = 8[tex]\implies \dfrac{f(8)-f(0)}{8-0}=\dfrac{0-4}{8-0}=-\dfrac{4}{8}=-\dfrac{1}{2}[/tex]

The students at Emir's school voted for a new school color. 738 students voted for orange and the other 82 students voted for yellow. What percentage of the students voted for yellow?
We can conclude that 10 percentage of the students voted for yellow.
What do we mean by percentage?A percentage is a number or ratio expressed as a fraction of 100 in mathematics. The percent sign, "%," is commonly used, but the abbreviations "pct.", "pct," and sometimes "pc" is also used. A percentage is a number with no dimensions; it has no unit of measurement.Total number of students = 738 + 82 = 820
As we can notice that total number is 820 and the number of students that voted for yellow is 82.
So, 82/820 = 10%
Therefore, we can conclude that 10 percentage of students voted for yellow.

plot the image of point Q under the translation (x,y) —— (x-3,y+4)
Considering point Q (x, y) to be (1, 2), and translating it by (x-3, y+4), the image of point Q, say Q' will be positioned at (-2, 6), which is plotted in the reference image attached hereby.
As per the question statement, we are required to plot the image of point Q(x, y) under the translation (x-3, y+4).
Let us assume the point Q to be (1, 2). Therefore, a translation of (x-3, y+4) on (1 , 2) will result in a new position, which will be:
3 units to the left of (1, 2) along the x-axis, and then 4 units upwards along y-axis.
Hence, the position of the image of Q (1, 2) after a translation of (x-3, y+4) will be Q' [tex][(1-3), (2+4)]=(-2, 6)[/tex].
Both the points Q(1, 2) and its image after the translation of (x-3, y+4), Q'(-2, 6) are plotted in two separate graphs, attached hereby for reference.

-6 and -4
The coordinate of the midpoint of the segment with the given endpoints is (-1, 0)
Midpoint of a lineThe midpoint of a line is the point that divides the line into two equal parts.
The formula for calculating the midpoint is expressed as;
M(x, y) = (x₁+x₂/2, y₁+y₂/2)
