Write an equation for the following graph. Keep your slope as a fraction.

Answers

Answer:

y= 10/3x + 20

Step-by-step explanation:

the slope is 10/3 because from one point to another (on the line) it moves up 10 (from 20 to 30) and to the right 3 (from 0 to 3)

the y intercept is 20 because when x = 0, y = 20 which we can see on the graph

y=10/3x +20

40%
10%
45%
12%

Answers

Answer: 12/30

and 40 percent

Step-by-step explanation:

Well it’s 12 to 30 so just put a fraction bar

and 12 divided by 30 is .4

Answer:

The answers are 12/30 and 10%

Step-by-step explanation:

It's 40% because the ratio of males to total students is 12 to 30, or 12:30, which is equal to 12/30.

The other answer is 10% because the ratio of males to total students is 3 to 30, or 3:30, which is equal to 1/10. Then you would do 100 divided by 10 which would give you 10 so it's 10%.

Hope this helps!

Answer:

Can I please have Brainliest I want to level up

Step-by-step explanation:

Can i get the right answers please

Answers

Answer: For the first question, m = 1.5 and y-intercept = 5, so your equation for the first one should be, y = 1.5x + 5.

And for the second question, m = -1.75 and y-intercept = 4, so your equation for the second one should be, y = -1.75x + 4.

Step-by-step explanation: For the 1st one, subtract 3x to get -2y = -3x - 10, then divide by -2 to get y = 1.5x + 5.

For the 2nd one, subtract 7x to get 4y = -7x + 16, then divide by 4 to get y = -1.75x + 4.

Hope this helps you! :)

prove tan(2x) = tan(x+x)

Answers

So here is how we are going to prove that (2(tan x - cot x) / (tan^2 x - cot^2 x} = sin (2x). Follow it step by step:
LS = 2(tanx−cotx)

tan^2−cot^2x
= 2(tanx−cotx)

(tanx−cotx)(tanx+cotx)

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

The variable feet and yards are in direct proportion.

Let,

yard = k(feet).

1 = 3k

k = 1/3 = 0.33.

A river current carried a fallen tree branch 1 over 3 of a mile in 1 over 4 of an hour. At what speed is the water in the river flowing, in miles per hour?

Answers

the answer is one and one over three

In miles per hour, 4/3 speed represents the flow of water in the river, and its calculation can be defined as follows:

Speed calculation:

Distance = [tex]\frac{1}{3}[/tex] miles

Time= [tex]\frac{1}{4}[/tex] hours

speed=?

Speed Definition:

An object's speed is indeed the pace at which it moves along a path in time, whereas its velocity is the rate and direction of travel.

The formula for calculating the speed:

[tex]\to[/tex] speed =[tex]\bold{\frac{Distance}{time}}[/tex]

               [tex]=\frac{\frac{1}{3}}{\frac{1}{4}}\\\\={\frac{1}{3} \times \frac{4}{1}}\\\\={\frac{4}{3}}\\\\[/tex]

Therefore, the calculated speed of water flow is [tex]\frac{4}{3}[/tex] miles per hour.
