What is a proportion?A proportion can be defined as an equation which is typically used to represent (indicate) the equality of two ratios. This ultimately implies that, proportions can be used to establish that two ratios are equivalent and solve for all unknown quantities.
In Mathematics, the graph of any proportional relationship is characterized by a straight line because as the values on the x-axis (x-coordinate) increases or decreases, the values on the y-axis (y-coordinate) increases or decreases simultaneously as shown in tables B and C.
In conclusion, tables B and C comprises data values that shows proportional relationship in a graph.

The two lines at right represent the growing profits of Companies A and B. Homework Help ✎ Sketch this graph on your paper. If Company A started out with more profit than Company B, determine which line represents A and which represents B. Label the lines appropriately. In how many years will both companies have the same profit? Approximately what will that profit be? Which company’s profits are growing more quickly? How can you tell?
Answers
Using concepts of linear functions, it is found that:
They will have the same profit after 3 years.This profit will be of $65,000.Due to the higher slope, Company B profit is growing more quickly.What do the slope and the intercept of a linear function represent?The slope-intercept representation of a linear function is:
y = mx + b.
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).Two linear functions have the same value when they intersect each other, hence, from the graph given at the end of the answer, they intersect around point (3,65), meaning that they will have the same profit after 3 years, and this profit will be of $65,000.
From the Graph, as it assumes higher values as n goes to infinity, company B has the higher slope, hence it's profit is growing more quickly.

The point (-4,1) is rotated 180 degrees counterclockwise using center (-3,0). What are the coordinates of the image?
Answers
By using a rotation rule, the image of point P = (- 4, 1) after rotating 180° counterclockwise using center (- 3, 0) is equal to point P'(x, y) = (- 2, 1).
How to determine the coordinates of the image of a point by using a transformation ruleIn this problem we find the case of a point that must be rotated 180° counterclockwise (+ 180°) about the point (- 3, 0). Rotation is a kind of rigid transformation, that is, a kind of transformation applied on a point such that Euclidean distance is conserved. The rotation formula for a point P(x, y) = (x, y) around the center O(x, y) = (Ox, Oy) is introduced below:
P'(x, y) = (Ox + (x - Ox) · cos θ - (y - Oy) · sin θ, Oy + (x - Ox) · sin θ + (y - Oy) · cos θ)
Where θ is the angle of rotation.
If we know that O(x, y) = (- 3, 0), P(x, y) = (- 4, 1) and θ = 180°, then the coordinates of the image are:
P'(x, y) = (- 3 + [- 4 - (- 3)] · cos 180° - (1 - 0) · sin 180°, 0 + [- 4 - (- 3)] · sin 180° + (1 - 0) · cos 180°)
P'(x, y) = (- 3 - [- 4 - (- 3)], - 1)
P'(x, y) = (- 3 - (- 1), - 1)
P'(x, y) = (- 2, - 1)
The coordinates of the image are P'(x, y) = (- 2, 1).

Answer:
Rational
Step-by-step explanation:
what property is 3x+2x+1-7=x+22
Answers
The property used is associative property.
If you need to solve it, here’s how:
First, combine the like terms of the constants (numbers that aren’t multiplied by a variable) by subtracting 1 by 7. This gets -6
3x + 2x -6 = x + 22
Now combine the like terms of the coefficients (numbers that are being multiplied by a variable) by adding 3x to 2x. This gets 5x.
5x - 6 = x + 22
You now want to remove the 6 because it is on the side of a coefficient. Remove it by adding 6 to -6 to get 0. Make sure to do this on both sides.
5x - 6 + 6 = x + 22 + 6
5x = x + 28
Now you can see that there is a variable (x) on the side of a constant (28), remove the x by subtracting x. Do this to both sides. All x’s automatically equal one because it is unknown.
5x - x = x - x + 28
4x = 28
Divide by 4 on both sides.
4x/4 = 28/4

feet. The total time for the dive so far was 19 1/8
minutes. What was the rate of change in the diver's elevation during the ascent? Round your answer to the nearest hundredth.
Answers
The rate of change of the divers elevation = 19.274
Given,
The depth to which the Scuba dove = -69 [tex]\frac{9}{10}[/tex] feet
The rate at which he dove = -21.5 feet per min.
The time which he spent at the elevation = 12.5min.
The elevation the diver then ascended to -38 [tex]\frac{9}{10}[/tex] feet
Thee total time for the dove = 19 [tex]\frac{1}{8}[/tex] minutes.
Therefore, the time [tex]t_{d}[/tex] with which the scuba diver descended to -69 [tex]\frac{9}{10}[/tex] feet
is given as follows:
[tex]t_{d} = \frac{Distance}{speed}[/tex] = [tex]= \frac{-69\frac{9}{10} }{-21.5}= \frac{-681}{-21.5}[/tex] = 3.167 minutes
The time [tex]t_{e}[/tex], it took the scuba diver to elevate to -38 [tex]\frac{9}{10}[/tex] feet is given as follows:
[tex]t_{e}[/tex] = 19 [tex]\frac{1}{8}[/tex]minutes - (3.167 + 10.5) minutes = 5.458 minutes
The rate of change of the divers elevation = (Final elevation - Initial elevation)/(Time taken).
∴ The rate of change of the divers elevation
= (-38 [tex]\frac{9}{10}[/tex] - (-69 [tex]\frac{9}{10}[/tex] )) / 5.458 min
=(37.1 - (-68.1))/ 5.458 min

Answers
by using multiplication, we get that 28 BLT sandwiches can be made by Omar.
We are given that:
For every full head of lettuce used,
Number of tomatoes used = 5
Now, we will use multiplication.
2 full heads of lettuce used = 5 × 2 = 10 tomatoes used
Now, we also have:
2 tomatoes used = 1 1/20 pounds of bacon used.
= 21/20 pounds of bacon used.
1 tomato = (21 / 20) × (1 / 2) = 21 / 40 pounds bacon
10 tomatoes = (21 / 40) × 10 = 21 / 4 pounds bacon
Also,
3 / 4 pounds of bacon = 4 sandwiches
1 pound of bacon = 16 / 3 sandwiches.
21 / 4 pounds of bacon = (16 / 3) × (21 / 4) = 28 sandwiches
Therefore, by using multiplication, we get that 28 BLT sandwiches can be made by Omar.

Answers
Given picture is not a graph of inequality y < 6x + 1
In this question, we have been given a graph.
We need to determine whether the picture is a graph for the inequality y < 6x + 1 or not.
We know that the graph of equation y = 6x + 1 is a straight line and we represent a straight line graph by a solid line.
This graph represents a shaded region below dotted line. This means, this is the graph of inequality.
From this graph we can see that x-intercept of the equation is (2, 0) and y-intercept is (0, - 4)
If we find the x and y-intercept of y = 6x + 1 then it would be,
x - intercept = (-1/6 , 0)
y - intercept = (0, 1)
This means, given picture is not a graph of inequality y < 6x + 1
