3. The equation y = 19x describes the amount of money Jeff earns, where x is the number of hours he works and y is the amount of money he earns.
The table shows the amount of money Carl earns for different numbers of hours worked.
(a) How much money does Jeff earn per hour? Show your work on how you found the constant of proportionality.
(b) How much money does Carl earn per hour? Show your work on how you found the constant of proportionality.
(c) Who earns more per hour? Justify your answer by comparing the two. Please use complete sentences.
(d) Draw a graph that represents Carl’s earnings over time in hours. Remember to label the axes with the real world quantities that x and y represent.
( please add a graph!! )

Jane invests £300 at a simple interest rate of 4.5% per year. At the end of each year, Jane gives the interest to a charity Work out the least number of years it will take for the total amount given to the charity to be greater than £50. Show your workings.
Answers
Answer:
At least 4 years
Step-by-step explanation:
Simple interest is given by
I = Prt
so here, one year's interest is
I = 300(.045) = 13.5
Divide 50 by 13.5 and get 3.7 years...thus
she will need four years to donate 50...
Step-by-step explanation:
Interest Rate = (Simple Interest × 100)/(Principal × Time).
given
Principal(P) = 300
Interest Rate(I.R) = 4.5%
Simple Interest(S.I) = 50
required
Time(T)
I.R = (S.I × 100)
(P ×T)
T × I.R = (S.I × 100) ×T
I.R (P × T) × I.R
T = (S.I × 100)
(P × I.R)
= (50 × 100)
(300 × 4.5)
= 5000

Answer:
18 since you have 13nd 3 that equal
Jack has 10
Kathy has 23
Vanessa has 26
10+23+26=59
To solve basically make Jacks money=x
Therefore
Kathys money= x+ 13
Vanessas money= x+13+3 (she has three more than Kathy cause it says Kathy has three less than her)
All of these terms together and make them equal to 59, combine like terms and solve for x (jacks money) which is 10

Which table represents a linear function?
Answers
Answer:Well, a linear function is proportional, a straight line (on a graph). And the numbers must not have the same answer. For instance, if the X input is 5, and the Y output is 7. And then another X input is 5, and the Y output is 8, that's non-linear.
So, the Answer would be the third graph. This is because the X values are steadily increasing, and so are the Y values.
For the X and Y values, for each time X increases by 1, Y increases by -8. This is, linear because both sides are constantly and evenly increasing.

Which train is faster? How do you know?
Answer[tex]\textbf{Amtrak is correct}[/tex]
Step-by-step explanation:
So First we have to figure out Has fast the trains go in 1 hour so we are going to divide...
Metra30 ÷ 2 = 15 Miles (Metra can go 15 Miles in one hour)
Amtrak80 ÷ by 5 = 16 (Amtrak Can go 16 Miles in one hour)
_______________________________________
So If Metra Were to keep going Here are the list of Miles Below
(45 Miles in 3 hours)
(60 Miles in 4 hours)
(75 miles in 5 hours)
________________________________________
Amtrak
(96 Miles in 6 hours)
(112 miles in 7 hours )
(128 miles in 8 hours)
Therefore, Amtrak is the Fastest Train

Multiply first cause it’s in the parentheses. To multiply fractions you go straight across
1/2 x 3/8
1 x 3 = 3
2 x 8 = 16
So you get
3/16
When dividing fractions you have to flip the second fraction and multiply the same.
So 3/4 divided by 3/16
Flip 3/16 to 16/3
So now
3/4 x 16/3
16 x 3 = 48
4 x 3 = 12
48/12

The image of the point (8, 6) dilated by a scale factor 1/2 is (4, 3)
The given point is (8, 6)
The scale factor of dilation = 1/2
To dilate a given point (x, y) by a scale factor m, multiply each of the coordinates (x, y) by m
The image = (mx, my)
For the point (8, 6) dilated by 1/2, the image will be calculated as shown below:
