The graph represents the amount of money Sal earns for babysitting.
Graph where the x- axis gives time in hours and runs from zero to three and beyond. The y- axis gives earnings in dollars and runs from zero to twenty four and beyond. A straight line intersects the axes at (0, 0). Its coordinates are (5, 4), (1, 8), (1.5, 12), (2, 16), and (2.5, 20)
Part A
What does the ordered pair (2.5, 20) represent in the situation?
A. $2.50 for 20 hours
B. $1 for 0.125 hours
C. $0.125 for 1 hour
D. $20 for 2.5 hours
Part B
Does the graph represent a proportional relationship? Explain.
A.
Yes. The line passes through the origin.
B.
Yes. The line has a variable rate of change.
C.
No. The slope is not constant.
D.
No. The line has a y-intercept greater than 0.
Part C
What is the linear equation represented by the graph?
A. y = 20x + 2.5
B. y = 2.5x + 20
C. y = 8x
D. y = 0.125x
Answer: d, a, and c
Step-by-step explanation:
Part(A)
The ordered pair (2.5, 20) represents $2.50 for 20 hours. the correct option is A.
Part(B),
Yes. the line passes through the origin. The correct option is A.
Part(C),
The linear equation represented by the graph is y = 8x. The correct option is C.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that coordinates are (0.5, 4), (1, 8), (1.5, 12), (2, 16), and (2.5, 20).
Part(A),
The ordered pair (2.5,20) represents that the earning is $20 for the work of 2.5 hours.
Part(B),
The slope of the line will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( 8 - 4 ) / ( 1 - 0.5 )
Slope = 4 / 0.5
Slope = 40 / 5
Slope = 8 hours
The y-intercept is calculated as,
y = mx + c
16 = ( 2 x 8 ) + c
c = 16 - 16
c = 0
Hence, the line passes through the origin.
Part(C),
The equation of the line will be written as,
y = mx + c
y = 8x + 0
y = 8x

−2 1/4=r−4/5
Help
Plz
Answer:
r=-29/20
Step-by-step explanation:
because
-2 1/4 will be -9/4=r-2/5 now you add 2/5 to both sides
witch means you have to increase the denominator to the greatest common denominator of 4 and 5 witch is 20 multiply the number used to combine with the denominator to get 20 to the numerator so itll be -45/20+16/20 witch will be -29/20 so there fore r=-29/20 or 1 9/20.

Answer:
44 °
Step-by-step explanation:
180- (84+52) = 44
Answer:
44 degrees
Step-by-step explanation:
A triangle has a total of 180 degrees.
First, add the 2 sides that are given to you:
84 + 52 = 136 degrees
Subtract 136 from 180 to find the remaining angle:
180 - 136 = 44 degrees
b = 44 degrees

Lattice has £15000 in a savings account at the start of the year. How much will she have at the end of the year if the annual interest rate is 7.5%?
Answer:
£13 875
Step-by-step explanation:
first you have to find out how much is 7.5% of 15 000 and you find it by calculating 0,075 times 15 000 which becomes 1 125. then you take out that answer from your first answer which is 15 000 - 1 125= 13 875
A player in a board game rolls a six-sided
number cube labeled 1 through 6 once.
Determine the theoretical probability of
rolling a 1 or 2.
Answer:
A six sided number from 1 to 6 is rolled in a game.
Step-by-step explanation:
Theoretical probability of rolling a 1 or 2.
1) The cube has 6 faces so the total number of the outcome would be 6 only.
2) As per the question we need only 1 or 2 so the favorable outcome would be 2.
3) P(E) = favorable outcome/ total number of outcome
P(E) = 2/6
P(E) = 1/3
Theoretical probability of rolling a 1 or 2 is 1/3

Mark wants to make an enclosure for his cows.
He has 44 metres of fencing.
He wants the width to be 8 metres less than the length.
What dimensions should the field have?
?
Answer:
the length and width be 15 meters and 7 meters respectively
Step-by-step explanation:
The computation of the dimension of the field is given below;
Let us assume the fencing be p
Length be x
And, the width be x - 8
So,
P = 44
P = x - 8 + x - 8 + x + x
= 4x - 16
Now
4x - 16 = 44
4x = 44 + 16
4x = 60
x = 15
And, the width be 15 - 8 = 7
So, the length and width be 15 meters and 7 meters respectively

Answer:
49π cm²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here diameter = 14, so r = 14 ÷ 2 = 7, then
A = π × 7² = 49π cm²
Answer:
49pi cm^2
Step-by-step explanation:
[tex]a = \pi \: {r}^{2} [/tex]
Because the radius is half of the diameter, divide it by 2 to get the radius to place in the formula which is 14 ÷2 = 7
so
A = pi × 7^2
A= pi × 49cm^2

Which equation could represent the relationship shown in the scatter plot?
A: y=−3/4x+10
B: y=−3x−2
C: y=−2/3x+1
D: y=9x−1/2
Answer:
A
Step-by-step explanation:
Use POE, none of the answer makes any sense
Answer: The correct answer would be A
Step-by-step explanation:
This question asks us what equation could represent the scatter plot. While we may not be looking for an exact line of fit we want one that can best represent the data that we have. While I would highly recommend graphing each equation as it would give you a much greater understanding of the material you can also piece together a correct answer just by looking at the equations. First of all, by looking at the graph we can tell that the slope is negative because as we progress along the x axis the values on the y axis get lower and lower meaning that we have a downward sloping line. This immediately narrows out D because we can see that there is no - sign before the 9x which represents the slope. We can also narrow out B right away as the slope is too extreme for our scenario. A slope of -3 means that it would have to be a lot more vertical than we see represented in this scatter plot. -3 means that the line would have to go down 3 units for every 1 unit it horizontally moves if that makes sense. Now we are left with two possible answer choices, A and C. We can now look at the y intercept point of these equations to determine the best answer. The y intercept is the point at which the line crosses the y axis. C has a y intercept of 1 and we see the scatter plot points congregate much higher on the y axis than 1 so that rules out that answer leaving us with A! Just to double check our answer we know a slope of -3/4x seems reasonable based on the previous information and we can certainly see that a y intercept of 10 would make sense! I hope this has been of use to you and please do not hesitate if you have anything you would like me to elaborate on :) Have a wonderful rest of your day!
Write a quadratic equation for a parabola with roots at (-2, 0) & (4,0) and a y-intercept at ( 0, -16) Write your answer in factored form
9514 1404 393
Answer:
y = 2(x +2)(x -4)
Step-by-step explanation:
The y-intercept will be a constant times the product of the roots. Here, the product of the roots is (-2)(4) = -8, so the constant of interest is -16/-8 = 2. That constant is the coefficient of the leading term of the quadratic, so is a multiplier of the factored form.
y = 2(x +2)(x -4)
