I think it is by multiplying by 2.
Step-by-step explanation:
Even if it depends on the x, the constant of proportionality just goes by the multiple of 2 as you can see on the graph.
For example, the point that's on ( 2, y) on the graph is the start of it's proportional relationship that is on the line. Here is an example of how it is proportional:

What is 5x-y=1/4 in slope intercept form? PLEASE give me step by step explanation and why you did what. Thank you! ❤
Answers
Answer:
y=5x-1/4
Step-by-step explanation:
The slope-intercept form would be y=mx+b, where y would be on one side. In this case, we would have to move y to one side. You can add y on both sides to move it on the right. Then, you would subtract 1/4 on both sides to move it to the left so that y is on its own side. Then the equation would equal y=5x-1/4, where 5 = m and -1/4 = b.
Answer:
The calculation to your equation is:
Y=5x-1/4

Answer:
Melinda saves 2 less dollars than Marcus each week.
Step-by-step explanation:
Y = 12x + 75 is Melinda's equation. Y = 14x + 25 is Marcus's equation. First we'll disregard how much money they have saved already to see how much they save weekly. So Melinda's new equation is Y = 12x, and Marcus's new equation is Y = 14x. Now we'll do Marcus's equation (14x) - Melinda's equation (12x) to see how much more money Marcus saves each week, which will in turn will tell us how much less money Melinda saves each week.
14 x - 12x = 2. (x-x=0) This tells us Marcus saves 2 more dollars than Melinda each week.
Which gives us our answer, Melinda saves 2 less dollars than Marcus each week.

This composite figure is made of three identical cylinders that are connected together
Radius:3 Height:8
Answers
SA = 2πr2 + 2πrh
where:
r = radius
h = height
This formula comes from adding the areas of the surfaces of the cylinder. It has two flat circular faces and a rounded face.
If we cut the cylinder from the circular face symmetrically, the surface area for one piece will be
SA = 2[(πr2)/2] + (2πr/2)h + 2rh
We will have 2-half flat circular faces, a flat rectangular surface, and half of the rounded surface.
Simplify the SA formula.
SA = πr2 + πrh + 2rh
SA = r(πr + πh + 2h)
Substitute the values into this formula.
SA = 3(3π + 8π + (2*8))
SA = 3(11π + 16)
SA = 33π + 48
SA = 151.67 cm2
Since we have 2 pieces, multiply this result by 2.
2(151.67 cm2) = 303.34 cm2.
The total area is 303.34 cm2.

1000000 x 1000000= what?
Answers
Answer:
1000000000000
Step-by-step explanation:
1000000x1000000=1000000000000
The solution of the expression 1000000 x 1000000 in exponential form is [tex]10^{12}[/tex].
A collection of constants, variables connected using one or more arithmetic operator is called an expression.
Example = 4y, 3x+4.
The way of writing or expressing a number in powers is called exponent.
Example: [tex]3^2[/tex]
Here, 3 is the base and 3 is the power.
The given expression can be written in the index or exponential form as:
1000000 x 1000000 = [tex]10^6 \times 10^6[/tex]
Since, the given exponent has the same base.
So, using the law of exponent, it can be written as:
[tex]a^m + a^n = a^{(m+n)[/tex]
[tex]10^6 \times 10^6 = 10^{(6+6)}[/tex]
= [tex]10 ^{12}[/tex]
Thus, the solution of the expression 1000000 x 1000000 in exponential form is [tex]10^{12}[/tex].
