Answer:
Option (D) is correct
Step-by-step explanation:
If y is a multiple of x and versa, it will have a constant of proportionality.
Option (A)
y = (81/3)xy
y will cancel out
1=27x
It is not correct
Option (B)
y=9xy
y will cancel out
1=9x
Option (C)
y=3xy
y will cancel out
1=3x
Option (D)
y = (1/9) x
y will cancel out
x=9y
In option (D), we see that x is 9 times of x. It means it has constant of proportionality equal to 9.
The equation y = 9x represents the constant of proportionality which is equal to 9.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation can also be used to represent direct proportionality as -
y = mx
m = y/x
[m] is called constant of proportionality
We have the constant of proportionality equal to 9
The equation y = 9x represents the constant of proportionality which is equal to 9 as when compared with y = mx, we get m = 9.
Therefore, the equation y = 9x represents the constant of proportionality which is equal to 9.

Answer:
Time would be the independent variable and tiles that was installed would be the dependent variable.
Step-by-step explanation:
Hope this helps you!!
If you have any more questions feel free to ask.
Answer:
Time is the independent variable, and tiles installed is the dependent variable.
Step-by-step explanation:
The independent variable is considered the input variable.
The depended variable is considered the output variable.
So, in other words, when you input x amount of time, there will be y amount of tiles installed.

A parking meter at a parking garage charges $4 per hour. Every fraction of an hour is rounded up to the next hour. What is the cost for parking a car in the parking garage for 312 hours
Answer:
$1,248.00, or 1,248 dollars.
Step-by-step explanation:
First, multiply 4, which is the dollars per hour, by 2, which is 8. Then, multiply four with ten, which is 40. Next, multiply 4 with 3, which is 12, and add two zeros on the back, which is 1,200. Finally, add them all together for a total of $1,248.00, or 1,248 dollars.

Hi I need help with this
Answer:
55
Step-by-step explanation:
90+35=125. 180-125=55. Answer: 55 degrees.
Answer:
Angle E = B. 55 degrees
Step-by-step explanation:
Every triangle's angles always add up to 180 degrees.
Angle F is marked as a 90 degrees angle, so we can then add 35 and 90 together to get 125.
Then, subtract 125 from 180 to get the measure of Angle E.
180 - 125 = 55
Angle E is measured at: B. 55 degrees.
