Please help! I need to tell whether x and y are in a proportional relationship and I need to write an equation that represents the relationship if it’s proportional.
Answers
Answer:
It is a proportional relationship
Step-by-step explanation:
To see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportional ratios.The equation that represents a proportional relationship, or a line, is y=kx, where k is the constant of proportionality.
Hope this helps
the constant of proportionality is 2

see explanation!
Step-by-step explanation:
Line N
A set of points where the coordinates of each point have a sum of 2Line M
A set of points where the y-coordinates of each point is 10 less than its x-coordinate
Any coordinate on N has a sum of 2.
Any coordinate on M has a y that is 10 less than the x.
The matching is shown below.
What are Coordinates?Coordinates are two integers (Cartesian coordinates) or a letter and a number that point to a specific place on a grid known as a coordinate plane. A coordinate plane has four quadrants and two axes: x (horizontal) and y (vertical).
First, A set of points where the coordinates of each point have a sum of 2
- Any coordinate on N has a sum of 2.

Answer:
120πcm²
Step-by-step explanation:
Since we are keeping this in terms of pi, you do not necessarily need a calculator. I will be doing my calculations as simple as I can.
First we need to figure out the area of the top circle and bottom circle.
We know that the formula for the area of a circle is:
πr²
So we need both circles, our formula becomes:
2πr²
Let's substite our radius in.
2 × π × 4² = 32πcm²
Now we need to find the area of the sides itself. Our formula here is:
2 × π × r × h
Let's substitute our radius and height in:
2 × π × 4 × 11 = 88πcm²
Let's now add both of these together:
88πcm² + 32πcm² = 120cm²
Remember to add your measurements!
Hope this helped!

How do you solve a y=mx+b equation if x is unkown?
example -
y = 1.29x+2
How do I solve that? Please make sure to explain :) thanks!
Answers
Answer
Y= 2 x= -0.645
Step-by-step explanation:
you basically plug 0 into x and y
y=1.29(0)+ 2
y=2
0=1.29x+ 2
Answer:
Okay so "y = mx+b is a linear equation that represents a line on a graph; m represents the slope of the line and b is the y-intercept (The y-intercept of this line is the value of y at the point where the line crosses the y axis.)
In y = 1.29x+2, 1.29 is equal to m, so that is your slope.
The 2 is equal to the b so your y-intercept is 2.
Here's a graph to better understand it :)
