The equation y = 16.50x describes the amount of money Joey 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 Kaylee earns for different numbers of hours worked.
Kaylee’s Earnings
Time (h) 2 5 8 10
Money earned ($) 39 97.50 156 195
(a) How much money does Kaylee earn per hour? Show your work.
(b) Who earns more per hour? Justify your answer.
Answer:
(a)19.5 per hour
(b)Kaylee earns more per hour.
Step-by-step explanation:
a.) To find the unit rate/hourly rate :
39÷2=19.5 per hour.
b.)Kaylee eanrs more considering that Joey earns 16.50$ per hour as opposed to 19.50$ per hour.
Answer:
(a) Kaylee earns $19.50 per hour.
(b) Kaylee earns more money per hour than Joey.
Step-by-step explanation:
x = # of hrs. worked
y = amount of money earned
Joey:
y = 16.50x
Kaylee:
Time (h) 2, 5, 8, 10
Money earned ($) 39, 97.50, 156, 195
y = mx + b; Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
We will be using: (2,39) and (8,156) to find the slope of this table.
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{156-39}{8-2} \\\\m=\frac{117}{6} \\\\m=19.5[/tex]
y = mx + b
y = 19.5x + b
I will be using (2, 39) to find the value of b
(2, 39)
y = 19.5x + b
39 = 19.5(2) + b
39 = 39 + b
-39 -39
0 = b
y = 19.5x + b ==> y = 17.7x + 0 = OR y = 19.5x (since the value of b is 0)
(a) The question wants us to find out how money Kaylee earns per hour. Recall that x = # of hrs. worked and y = amount of money earned.
y = 19.5x
She earns $19.50 per hour.
(b)
Joey: y = 16.50x (earns $16.50 per hour)
Kaylee: y = 19.5x (earns $19.50 per hour)
As you can see, Kaylee earns more money per hour than Joey.

What is the product of 7 Over 9 and One-fourth?
7 Over 36
8 Over 36
7 Over 13
8 Over 13
Answer:
7 over 36
Step-by-step explanation:
You just multiply side by side
Answer:
[tex]\frac{7}{36}[/tex] 7/36
Step-by-step explanation:
in order to find the product of 2 fractions you need to first make sure that they both have common denominators. in order to find the common denominators you need to find the LCM (lowest common multiple) of the two denominators
so 7/9 and 1/4 the lcm of 9 and 4 is 36
[tex]\frac{7}{9}[/tex] x 4 = [tex]\frac{28}{36}[/tex] [tex]\frac{1}{4}[/tex] x 9 = [tex]\frac{9}{36}[/tex] 28/36 x 9/36 = 28 x 9 = 252/36 = 7 /36

Raven plans to increase the price of each item in her store by 10%. Which the following sets of steps could Raven use to find the new price of each item. Place a checkmark in the box next to each correct set of steps.
A. Multiply the price of each item by 10%
B. Multiply the price of each item by 1.1
C. For each item, multiply its price by 0.1 and then add that product to the original price of the item.
D. Multiply the price of each item by 0.9
E. For each item, divide the price by 10 to find 10% of the item and then multiply that quotient by 11 to find 110% of the origional price.
Answer:
Step-by-step explanation:
B is correct as 1.1 = 110%
C is correct as adding (0.1 multiply original price) = 1.1 = 110%
E is correct as dividing original price by 0.1 then multiplying by 11 = 1.1 = 110%
Correct Answer: B, C
Choice A only finds the amount that is increased by, not the new price
Choice D is if the original price is discounted by 10%
The second part of Choice E does not make sense
Basically, here is how you find the new price:
Let the original price be x.
New Price = x * (1 + 10%) = x * (1 + 0.1) = x * 1.1
Write the equation of the line with slope 1 and y-intercept 5.
Answer:
Slope intercept form;
y = mx b
where y is the dependent variable and x is the independent variable
m is the slope
and b is the y - intercept
So if we just plug in what we have;
Slope of 1x and a y - intercept of 5, we would get:
y = 1x + 5
Pls answer question. Show working
Answer:
-2x + 5
Step-by-step explanation:
y-5= -2(x-0)
y= -2x + 5

The figure below is divided into 100 small squares of equal size.
How much of the figure is shaded?
Give the amount as a fraction and as a decimal.
Answer:
Fraction: 6/10 Decimal: 0.6
Step-by-step explanation:
There are 100 blocks and 60 are shaded. If you take the last zero off of both numbers you get 6 and 10. The larger number is the denominator because the denominator is always larger otherwise its an improper fraction. That leaves the 6 as the numerator so there is your fraction. Next, just convert it into a decimal as you're done!
You are having a pizza - making party.
You will need 6 ounces of dough and 4 ounces of sauce for each person ( including yourself, the host ) .
Once you have a total count of guest, you buy exactly the needed amount of all the ingredients . The dough and sauce that you buy weigh 130 ounces all together.
1. How many ounces of dough did you buy?
2. How many ounces of sauce did you buy?
3. Num. Guest 0ω0
Worth 10 points . . .
Answer:
12 guests(13 including yourself), 78 ounces of dough, and 52 ounces of sauce.
Step-by-step explanation:
So what you want to do is to first add up the dough and the sauce which is 10. then you want to divide 130 by 10 and you get 13(130/10=13) Now we subtract 1 from 13 and that how many guests you have which is 12. now we time 6 by 13 which is 78(6*13=78) so 78 ounces of dough. Now we time 4 by 13 and we get 52(4*13=52) so 52 ounces of sauce. Now to make sure it's right we need to add 78 and 52 together and we get 130(78+52=130) And that's all

Which point is not on the graph of the function y = x - 4?
(5, 9)
(234, 230)
(7, 3)
(12, 8)
Option A is correct, (5, 9) is the point not on the graph of the function y = x - 4.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given function is y=x-4.
Let su check all the given points whether they are point of the given graph or not.
The point (5, 9) is not on the graph of the function y = x - 4
Because when x = 5, y = 1, not 9.
The point (234, 230) is on the graph of the function y = x - 4
Because when x = 234, y =230
The point (7, 3) is on the graph of the function y = x - 4
Because when x = 7, y =3
The point (12, 8) is on the graph of the function y = x - 4
Because when x = 12, y =8
Hence, (5, 9) is the point not on the graph of the function y = x - 4.

Which sequences of transformations confirm the congruence of shape II and shape I?
a reflection of shape I across the x-axis followed by a 90° clockwise rotation about the origin
Answer and Step-by-step explanation:
A reflection of shape I across the y-axis followed by a 90° clockwise rotation about the origin
The sequence of transformations stated is correct.
First, the shape will be reflected across the y-axis. So essentially, make all the x-value points the opposite (turn positive values to negative, and negative values to positive; in this case, turn the positive x-values to negative x-values.)
Then, you rotate the figure 90 degrees counterclockwise (going up, not to the right on the graph, like how the minute and hour hand move around the clock.) The points will line up with shape II.

Use point-slope form, y - y1 = m(x - x1), to find the linear equation of a line that passes through the points
(2, -1) and (10, 7).
y = _x+ _
Answer: y = 1x -3
The 1 is not necessary so
y= x - 3
Step-by-step explanation:
(y- y1) = m(x -x1). First
Substitute y and x-values from the given coordinates and solve for x.
7-(-1)=m(10-2)
8 = m(8) 8/8=1 T
m= 1 The slope, m is 1
Then substitute values of y and x from either given coordinate into the equation and solve for b, the y-intercept.
y=mx+b
-1= 1(2)+b
-1=2+b subtract 2 from both sides.
-1-2 = b
-3 = b
OR
7= 10 + b
-10 +7 = b
-3 = b
Finally, write the equation with the values for m and b
y = 1x +(-3) Simplify & Rewrite
