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 1

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

Emily had 30 cookies to bring to school for her birthday. Three students wanted two cookies each. Then, a new student came that day and he wanted three cookies. Then, one of the three kids gave their cookies back. Emily was still passing out cookies. How many cookies did Emily have Pass out After the Student gave their Cookies Back?

Answers

30-6=24-3=21+2=23

3x2=6

Não sei se é isso

Ok, let’s see here. Emily had a total of 30 cookies, and right off the bat 3 students wanted 2 cookies. 3 times 2 is 6, so that’s already 6 cookies taken away. 30 minus 6 is 24, so currently she has 24 cookies left. Then, one of those 3 kids gave only ONE cookie back, so we take 24, and add 1. Giving us 25. We are trying to see how many cookies Emily has passed out so far, so we take the original number, which is 30, and subtract that by our current number which is 25. Giving us 5, meaning she has passed a total of 5 cookies so far.

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.

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!
