Josephine is opening a retail shoe store and has developed this graph to represent her projected revenue, costs, and profit. Which two
sentences correctly interpret the graph?
20.000
revenue
Dollars
costs
profits
50
Profits increase until the price of the shoes reaches $22.
Costs decrease until the price of the shoes reaches $22,
Answer:
Profits increase until the price of the shoes reaches $22.
There are more prices with positive revenues than positive profits.
Step-by-step explanation:
In the picture attached, the problem is shown.
The first sentence is true because the profit curve has a maximum at $22.
The second sentence is true because the profit is computed as follows:
profit = revenue - cost
and cost decreases as the price increase; therefore, there are positive revenues with negatives profits.
The two sentences which correctly interpret the graph include:
Profits increase until the price of the shoes reaches $22.There are more prices with positive revenues than positive profits.What is a Graph?This is defined as a pictorial representation of numbers or variables in an organized manner.
The profit curve has a maximum at $22 which makes statement 1 correct while from the graph we can also deduce that there are more prices with positive revenues.

A line parallel to the___ has no defined slope, and a line parallel to the_____ has slope of zero.
1) X-axis. 2) x-axis
Y-axis
y-axis.
Answer:
A line parallel to the y-axis has no defined slope, and a line parallel to the x-axis has slope of zero.
Step-by-step explanation:
Lines parallel to the y-axis are vertical and are undefined as they don't technically have a gradient.
lines parallel to the x-axis are horizontal and have a gradient of 0 since there is no positive or negative angle, it's just straight.

Answer:
Inverse of -5-9x/x-6
Step-by-step explanation:
Steps:
1: Interchange the variables x and y.
x=6y-5/y+9
2: Solve x = 6y-5/y+9 for y
3: Multiply both sides by y+9
4: Simplify and Expand
5: Subtract 9x from both sides.
6: Simplify and Subtract y from both sides then Simplify again
7: Divide both sides by x-6
Answer: Inverse of -5-9x/x-6

Ellie compared 4/7 and 5/3 by first comparing each fraction to 1/2 and 1.
Step 1: 4/7 is less than 1 but more than 1/2
Step 2: 5/3 is more than 1
Step 3: so, 4/7 > 5/7
In which step did
Ellie make her first mistake?
Answer:
Step 3
Step-by-step explanation:
She made her first mistake in Step 3.
This is because 4/7 is actually less than 5/3.
Step 1 and 2 are mathematically accurate.
1/2 is less than 1.
So, since 4/7 is only greater than 1/2 and not greater than 1 as compared to 5/3 which is actually greater than 1, she should have concluded that 4/7 is less than 5/3.
Therefore, Step 3 contains the mistake.

You use a garden hose to fill a wading pool if the water rises 12 cm or seven minutes and you record the data point of (21,y) What is the value of Y?
Answer:
The rate of change at which the water level rise is 13/6 cm/minute.The slope of the line is 13/6.The value of y is 23, (12,23).
Step-by-step explanation:
In the question the water rises 13 cm every 6minutes. Taking x to represent the time in minutes and y to represent the rise in cm then, find the rise y in time x as;
6 minutes=13 cm
1 minute=?---------------------perform cross multiplication
(1*13)/6=13/6
Hence in 1 minute, the rise is 13/6 cm
Thus in 12 minutes, the rise will be ;
12 * 13/6 = 2*13= 26 cm
(x,y) will be (12,26)
Finding the slope of the line using point (6,13) and (x,y)
The rate of change at which the water level rises equals the slope of the line.This is the justification.

Part B
If he has saved $9
from his allowance, how much more money does Tom need to buy all three books?
Answer:
part a: $33.50
part b: $24.50
Step-by-step explanation:
add up all of the costs of the books so 19.50 + 8.50 + 5.50 = $33.50
next just subtract 9 dollars from 33.50 so 33.50 - 9 = $24.5 more he needs.

If a family of 5 would like to attend one game during the football season and one during the baseball season how much would it cost them. How much was the average price of a football game ticket last year to see the Giants, how about the average price of baseball ticket to see Yankees Play?
Answer:
just read through this document
The cost of a baseball ticket is $26.64 and the cost of a football ticket is $74.99.
If a family of 5 would like to attend one game during the football season and one during the baseball season,
The cost of a baseball ticket is $133.2 and the cost of a football ticket is $374.95.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given:
For the 2009 Major League Baseball and National Football League seasons, based on average ticket prices,
Three baseball tickets and two football tickets would have cost $229.90, while two baseball tickets and one football ticket would have cost $128.27.
Let x represents the cost of one baseball ticket and y represents the cost of a football ticket.
Then,
3x + 2y = 229.90
2x + y = 128.27.
The solution of the system of the equation is the intersection point of the line.
The solution = (26.64, 74.99)
The cost of a baseball ticket is $26.64 and the cost of a football ticket is $74.99.
If a family of 5 would like to attend one game during the football season and one during the baseball season,
the cost of a baseball ticket is $26.64x 5 = $133.2 and the cost of a football ticket is $74.99x5 = $374.95.
Therefore, all the required value is given above.

The diagram shows a square pyramid over a cube. What is the volume of the entire figure?
Answer: 810
Step-by-step explanation:
first lets take down the information we were given,
height (h) of the pyramid should be 12 - 9 = 3
base (a) = 9
So we calculate the volume of a square pyramid
V = a²h/3
V = (9² × 3) / 3
v = (81 × 3) / 3
V = 81
now we calculate the volume of the cube using the formula
V = a³
V = 9³
V = 729
NOW to get the volume of the entire figure
we say
volume of square pyramid + volume of cube
81 + 729 = 810

The coordinates of the endpoints of the diameter of a circle are (3,7) and (-5,3). Find the coordinates of the center of the circle
Answer:
[tex](-1,5)[/tex]
Step-by-step explanation:
The definition of the diameter indicates it passes through the center of the circle to be called diameter. Therefore finding the midpoint of the line that is the diameter we will find the center of the circle.
To find the coordinates of this midpoint we must make an average of the 'x' values of the two given points, and also an average of the two given 'y' values.
the coordines of this midpoint will be [tex](x_{m},y_{m})[/tex] where [tex]x_{m}[/tex] is the average of the 'x' values, and [tex]y_{m}[/tex] is the average of the 'y' values
The points we have are:
[tex](3,7)[/tex]
where I will call the coordinates: [tex]x_{1}=3[/tex] and [tex]y_{1}=7[/tex]
[tex](-5,3)[/tex]
where I will call the coordinates: [tex]x_{2}=-5[/tex] and [tex]y_{2}=3[/tex]
the average of the 'x' values is:
[tex]x_{m}=\frac{x_{1}+x_{2}}{2}[/tex]
substituting the values:
[tex]x_{m}=\frac{3+(-5)}{2}\\ \\x_{m}=\frac{3-5}{2}\\ \\x_{m}=\frac{-2}{2}\\ \\x_{m}=-1[/tex]
the average of the 'y' values is:
[tex]y_{m}=\frac{y_{1}+y_{2}}{2}\\[/tex]
substituting the values:
[tex]y_{m}=\frac{7+3}{2}\\ \\y_{m}=\frac{10}{2}\\ \\y_{m}=5[/tex]
and the center of the circle (the midpoint of the diameter) is at:
[tex](x_{m},y_{m})[/tex]
which is
[tex](-1,5)[/tex]
