You have a budget of $300 to order shirts for a math club. The equation 10x + 12y = 300 models the total cost, where x is the number of short-sleeved shirts and y is the number of long-sleeved shirts.
a. Interpret the terms and coefficients in the equation.
b. Graph the equation. Interpret the intercepts.
c. Find three possible solutions in the context of the problem.
Answers
a) The coefficients are the costs of the respective shirts.
b) The graph can be seen on the image at the end, the intercepts are (0, 25) and (30, 0)
c) 3 solutions are:
(0, 25), (30, 0), (25, 4)
What does each coefficient means?
Here we know that:
x = number of short-sleeved shirtsy = number of long-sleeved shirts.And we have the linear equation:
10x + 12y = 300
The first coefficient is the one in the term "10x"
The coefficient 10 will mean the cost, in dollars, of each short-sleeved shirt.
The second coefficient is on the term "12y"
And 12 means the cost in dollars of each long-sleeved shirt.
b) The graph of the linear equation can be seen on the image at the end.
The y-intercept (when x = 0) is the number of long-sleeved shirts you can buy if you don't buy any short-sleeved one.
The x-intercept is the number of short-sleeved shirts you can buy if you don't buy any long-sleeved one.
c) 3 possible solutions can be seen on the graph, some examples are:
(0, 25), (30, 0), (25, 4)

Teddy and Henry both bought a used car on the same day. Teddy's used car has
4,298 miles on it already, and he drives 426 miles per month. Henry's car has 6,129
miles on it already, and he drives 223 miles per month. After how many months will
each car have the same nulaber of miles on it?
Answers
After 9 months each car will have the same number of miles on it.
What is a linear equation?
Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.
Here,
Let miles per month be x.
then, by a linear equation, we get
4298 + x(426) = 6129 + x(223)
203x = 1831
x = 9 months
Hence, after 9 months each car will have the same number of miles on it.

Calculate (A) amount to be credited and (B) balance outstanding: (Round your answers to the nearest cent.) Invoice: $3,000; Terms 2/10, n/30 Invoice date: July 5 Payment amount $600 Date paid: July 14
Answers
The amount to be credited, based on the invoice amount and the payment, is $612.24. The balance outstanding is $2, 387.76
How to find the balance outstanding?Credit terms of 2/10, n/30 mean that if a buyer pays their payables in 10 days, they get a 2% discount. If they don't, then they'd have to pay the full thing in 30 days.
The days till the partial payment was made was:
= July 14 - July 5
= 9 days
The discount of 2% would apply on the payment of $600 so the amount to be credited is:
= 600 / (1 - 2%)
= $612.24
The balance would then be:
= Invoice amount - credited amount
= 3, 000 - 612.24

Riley wants to find the smallest of the fractions One-sixth, Eleven-twelfths, Five-sixths, and Ten-twelfths. She uses 0 and 1 as benchmarks. Which fraction is closest to 0?
Answers
Answer: 1/6
Step-by-step explanation: Make all of the denominators the same. The least common multiple of 6 and 12 is 12. 1/6 gets multiplied by 2/2 to the equivalent fraction 2/12. 11/12 stays the same. 5/6 is multiplied by 2/2 to get 10/12. 10/12 stays the same. 1/6 is the smallest fraction so it is the closest to 0.
Given g(x) = −2x^2 + 3x + 20, find g(0), g(−2.5), g(4), g(0.75), g(20)
Answers
The functions g(0) = 20, g(−2.5) = 0, g(4) = 0, g(0.75) = 21.125, g(20) = -720 as a result of the mapping with the function g(x) = −2x² + 3x + 20
What is a function?A function is a mapping whose codomain is the set of real numbers. It can also be defined as a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
From the function g given as g(x) = −2x² + 3x + 20, by careful mapping we have the following;
put 0 for values of x
g(0) = -2(0)² + 3(0) + 20
g(0) = 20.
put -25 for values of x
g(-25) = -2(-25)² + 3(-25) + 20
g(-25) = -12.5 - 7.5 + 20
g(-25) = 0
put 4 for values of x
g(4) = -2(4)² + 3(4) + 20
g(4) = -32 + 12 + 20
g(4) = 0
put 0.75 for values of x
g(0.75) = -2(0.75)² + 3(0.75) + 20
g(0.75) = -1.25 + 2.25 + 20
g(0.75) = 21.125
put 20 for values of x
g(20) = -2(20)² + 3(20) + 20
g(20) = -800 + 60 + 20
g(20) = -720
Therefore, by proper mapping of the function g(x) = −2x² + 3x + 20, we derived g(0) = 20, g(−2.5) = 0, g(4) = 0, g(0.75) = 21.125, and g(20) = -720.

Answers
Stock used to sell for $105.81 ten years ago.
[tex]CAGR = ((\frac{EV}{BV} )^{\frac{1}{n}}-1)*100[/tex]
Here, CAGR = Compounded Annual Growth Rate = -2.3%
EV = Ending Value = x
BV = Beginning Value = $83.80

A teacher covered the exterior of a rectangular prism-shaped box that measured 8 inches by 9 inches by 10 inches using one sheet of rectangular-shaped wrapping paper that measured 2 feet by 3 feet. There were no gaps or overlapping paper. How many square inches of wrapping paper were left over?
Answers
The number of square inches of the wrapping paper left over is 380 square inches
How to determine the amount of square inches left?From the question, we have the following parameters that can be used in our computation:
Box:
Dimension = 8 inches by 9 inches by 10 inches
Rectangular-shaped wrapping paper
Dimension = 2 feet by 3 feet.
The surface area of the box is
Box = 2(lw + lh + wh)
So, we have
Box = 2 * (8 * 9 + 8 * 10 + 9 * 10)
Evaluate
Box = 484 square inches
The surface area of the wrapping paper is
Wrapper = lw
So, we have
Wrapper = 2 * 3
Evaluate
Wrapper = 6 square feet
Convert to square inches
Wrapper = 864 square inches
The amount of square inches left is
Amount left = Wrapper - Box
Amount left = 864 square inches - 484 square inches
This gives
Amount left = 380 square inches
Hence, the amount left is 380 square inches

The equation of line with a slope of 3/2 which passes through point (-4,-2) is y = (3/2)x + 4.
What is the equation of line with the given point and slope?
The equation of line is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
Given the data in the question;
Point (-4, -2 )
x = -4y = -2Slope m = 3/2First, we determine the y-intercept 'b'.
Plug the point and slope slope into the equation of line formula and solve for b.
y = mx + b
-2 = (3/2)(-4) + b
-2 = (3)(-2) + b
-2 = -6 + b
b = -2 + 6
b = 4
Now, plug the slope and y-intercept into y = mx + b to determine the equation of the line.
y = mx + b
y = (3/2)x + 4
Therefore, the equation of the line is y = (3/2)x + 4.

ou get an auto loan at 6% interest for 5 years; please answer the following. You can afford a $350 per month car payment; how expensive a car can you afford? (Round to two decimal places and do not include a dollar symbol)
Answers
You can afford a car at a price of 13,016.79
What is the monthly payment formula?
The monthly payments are given by the equation presented as follows:
[tex]A=P\frac{R(1+R)^{n} }{(1+R)^{n}-1 }[/tex]
where R = r / 12
P is the initial amount , r is the interest rate , n is the number of payments.
Given data ,
A = $ 350
R = 6 %
r = 6 / 12 %
= 0.5 %
= 0.005
n = 5 years
= 5 x 12 months
= 60
Therefore , the maximum value of the car is calculated as
[tex]A=P\frac{R(1+R)^{n} }{(1+R)^{n}-1 }[/tex]
[tex]250=P\frac{0.005(1+0.005)^{60} }{(1+0.005)^{60}-1 }[/tex]
[tex]250=P\frac{0.0067}{1.3488501-1}[/tex]
[tex]P = \frac{250*0.348850}{0.0067}[/tex]
[tex]P=\frac{87.2125}{0.0067}[/tex]
P = 13016.79
Hence , you can afford a car at a price of 13,016.79

Write an equation for the trend line shown on the scatter plot. ASP
Answers
Answer:
y=5x+15
Step-by-step explanation:
the equation of a line is y=mx+b where b is the y-intercept and m is the slope.
if you look at the graph you will see that your line intecpts the y axes at b=15 or that would be your y value where the line touches the edge.
now you just have to find your slope. slope is y/x or rise/run
so by looking at the graph at where our line touches the corner of a square. we just need to find 2 of those. we can use (0,15) and (1,20) the distance from 15 to 20 is 5 so that is our rise or change in y. the distance from 0 to 1 is 1 so that is our change in x or run. now just put rise over run so 5/1 which is just 5.
lastly we fill out our equation y=mx+b
our slop m is 5 and our y-intercept b is 15 so y=5x+15
