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]

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]

The lengths of the three sides of a triangle (in centimeters) are consecutive odd
integers. If the perimeter is 45 centimeters, find the value of the shortest of the three
side lengths.
Answer:
13, 15,17
Step-by-step explanation:
Let x = the first number
Let x + 2 = the second number
Let x + 4 = the third number
Consecutive means in order like 1,2,3 or 20,21,22. Consecutive odd means that you want three numbers in order that are odd. Each number would be 2 more than the number before. For example 5 + 2 = 7. We would have to add 4 to 5 to find the next consecutive odd number.
x + (x + 2) + (x +4) = 45 I put the numbers in parentheses so you could see the first number plus the second number plus the third number equals 45
x + x+ 2 + x+ 4 = 45 Combine like terms
3x + 6 = 45 Subtract 6 from both sides of the equation.
3x = 39 Divide both sides by 3
x = 13
Add 2 to that to get the next odd number.
Add 4 to 13 to get the third odd number.
Answer: 13 cm
Step-by-step explanation:
Let the value of the shortest of the three side lengths is x.
Since the three sides of a triangle are consecutive odd
integers, hence: x, x+2, x+4.
Thus,
[tex]P=x+(x+2)+(x+4)\\45=x+x+2+x+4\\45=3x+6\\45-6=3x+6-6\\39=3x\\[/tex]

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.

Part A: Rhett made $250 washing cars with his mobile car wash company. He charges $70 per car and earned $50 in tips. Write an equation to represent this situation. (4 points)
Part B: Scarlett made a profit of $250. 00 with her mobile car wash company. She charged $75. 00 per car wash and received $35. 00 in tips, but also had to pay $5. 00 in cleaning supplies per car wash. Write an equation to represent this situation. (4 points)
Part C: Explain how the equations from Part A and Part B differ. (2 points)
The equation for Rhett's Situation is 70x + 50 = 250 and the equation for Scarlett's Situation is 70x + 35 = 250. In Rhett's case equation their is no expense per car wash but in case of Scarlett' equation their is expense of $5 per car wash.
Total amount earned by Rhett = $250
Let the number of cars Rhett washed = x
Rhett charges $70 per car and earned $50 in tips. So, we can write
Total amount earned by Rhett = 70x + 50
On comparing total amount earned by Rhett, we get
70x + 50 = 250
The equation for Rhett's Situation is 70x + 50 = 250.
Total amount earned by Scarlett = $250
Let the number of cars Scarlett washed = x
Scarlett charges $75 per car wash and earned $35 in tips but also had to pay $5. 00 in cleaning supplies per car wash.. So, we can write
Total amount earned by Scarlett = 75x + 35 - 5x = 70x +35
On comparing total amount earned by Scarlett, we get
70x + 35 = 250
The equation for Scarlett's Situation is 70x + 35 = 250.
In Rhett's case equation their is no expense per car wash but in case of Scarlett' equation their is expense of $5 per car wash.

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.

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.
