A) -4 / 1 = -4
-12/3 = -4
-28/7 =-4
-60 /15 = -4
In this relationship, the value of y / x is constant. So, this is a proportional relationship.
B) 7.5 /1 =7.5
30/4 = 7.5
52.5/7 = 7.5
75/10 = 7.5
In this relationship, the value of y / x is constant. So, this is a proportional relationship.
C) 93.5 / -17 = -5.5
27.5/ -5 = 5.5
-11 / 2 = -5.5
-55 /10 = -5.5
In this relationship, the value of y / x is constant. So, this is a proportional relationship.
D) 7.5 / 5 =1.5
30 / -1 = -30
52.5 / 1 = 52.5
75/ 8 = 9.375
In this relationship, the value of y / x is not constant. So, this is a non-proportional relationship.

a box has width $m$, where $m$ is a prime number. if the box has height $m 2$, length $m-1$, and a volume of 140, what is $m$?
The width of the box m = 5 units
The width of the box = m units
Where m is a prime number
Height of the box = m+2 units
The length of the box = m -1 units
The volume of the box = 140 cubic units
The volume of the box = Length × width × height
140 = m × (m+2) × (m-1)
140 = (m^2 + 2m )(m-1)
140 = m^3 - m^2 + 2m^2 - 2m
140 = m^3 + m^2 - 2m
m^3 + m^2 - 2m - 140 = 0
We can split the equation by taking the common term outside
(m-5) (m^2 + 6m + 28) = 0
Therefore, one value of m = 5
5 is a prime number

how to do question no 9 b?
Answer:
4 records sold on Wednesday, 32 records sold on Thursday!
Step-by-step explanation:
To do 9b, you need to set up our own equation!
Let's use W to represent records sold on Wednesday and T to represent records sold on Thursday.
It said 36 total records were sold on Wednesday and Thursday. This can be represented with the following equation ...
W + T = 36
It also tell us that on Thursday (T), 8 times the number of records sold on Wednesday were sold on Thursday. In equation form, this looks like ...
T = 8 × W
Now, let's use all this info to solve!
Let's first solve the equation W + T = 36
But, we need values! We have one! We know what T equals!
Let's plug in T
T = 8 × W
W + ( 8 × W ) = 36
Solve
W + 8W = 36
9W = 36
W = 4
4 records were sold on Wednesday!
Let's plug in W in our T equation to see how many records were sold on Thursday.
T = 8 × W
T = 8 × 4
T = 32
32 records were sold on Thursday!
Wednesday can be represented with HALF A CIRCLE
and Thursday can we represented with FOUR CIRCLES

The company's profits on June 1, 2002 is $4500 and the company's profits many years into the future is $1000 per month.
The equation f(t) = (t^2 + 9) / (t^2+2) provides the monthly profits, in thousands of dollar, where t refers to months after June 1, 2002.

For calculating at what time did he start washing the window we need to subtract the time taken in cleaning the window from the time at which he finished washing.
As, for finding the starting time, we need to subtract 2 Hr. and 45 minutes from 3:05 PM.

Find the equation of the line, given the following information:
Passes through (-9,3) and is perpendicular to y =1/2x+6.
Answer:
y = -2x - 15
Step-by-step explanation:
We are given 2 pieces of information: (1) a point our line passes through, and (2) a line it is perpendicular to. The only thing we need from (2) is the slope.
We know that perpendicular lines have opposite signs and are inverses (denominator and numerator switched). So our line must have a slope of
m = -2
Using our equation for a line: y = mx+b, our line so far is
(I) y = -2x + b
Let's use the point we have (-9,3) and substitute what we know into equation (I) to find b.
x = -9
y = 3
(I) (3) = -2(-9) + b
3 = 18+b
b= -15
Now we have m and b so we can write the equation of our line:
y = -2x - 15

Sorry for weird format wouldve uploaded a picture of it but it wasn't working
The slope of the line is 3, equation of the line is y = 3x-2 and value of c is 4
What is a slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
Given that, All the given points are on the same line and the points are: (5,13) (c,10) (2,4)
Finding the slope;
We know slope of a line passing through two points = (y₂-y₁)/(x₂-x₁)
so, considering the points (5,13) and (2,4)
= (4-13)/(2-5) = 3
Therefore, the slope of the line is 3
Finding the equation,
We know the general equation of a line is given by, y = mx+b,
Where m is slope and b is y intercept.
Solving for b, put x = 5, m = 3and y = 13, in the equation
13 = 5x3+c
b = 13-15
b = -2
Therefore, the equation is y = 3x-2
Finding the missing coordinate c,
Since, all the points lies in same line, so slope will be equal in all the points,
Therefore, (10-13)/(c-5) = 3
c-5 = -1
c = 4
Hence, The slope of the line is 3, equation of the line is y = 3x-2 and value of c is 4

Zebra crossings, stacks of notebooks, and the nearby railroad tracks are just a few places where parallel lines can be observed. The distance between two parallel lines at their perpendicular intersections is constant.
Different shapes' sides go parallel to one another. The single arrow lines in the rectangle below are parallel to one another, and the double arrow lines are also parallel to one another.
The symbol for parallel lines is ||, which consists of two vertical lines placed between the names of the lines.
