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

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)
= 2
-------------------
(tanx+cotx)
= 2

Sin2x+cos2x

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.
