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.

What is the amount of discount? Explain how beaches are created. (ILL GIVE BRAINLIESTAND EXTRA POINTS IF U HELP ME ASAP!!!)It might not be well known, but there is a desert in North America. It spans along the western side of the continent, from southern Oregon to northern Mexico. It is mostly contained in the arid area between the Rocky Mountains to the east and the fertile coast of the Pacific Ocean to the west. Researchers estimate that the desert is between 500,000 and 730,000 square miles (1,300,000 and 1,900,000 square kilometres).People do live in this desert, but the pockets of people are dispersed and isolated. As a desert, the area is arid because of high evaporation, extreme temperatures, high winds, localized storms, and sun-beaten land. Life is a struggle in the desert for humans, as well as plants and animals. There are still descendants of indigenous desert cultures living in the desert. These Native Americans, along with European settlers, have added to the population of the region.In the desert, differences of latitude, elevation, climate, topography, vegetation, soil, and human use have divided the desert into a cold region and a hot region. The cold region of the desert is known as the Great Basin Desert. This area covers almost all of Nevada, western Utah, and sections of the neighboring states. South of this basin is the Mojave Desert, which is the hot region of the North American Desert. This area covers much of California, southern Nevada, and some of Mexico.What evidence does the author use to support the idea that there are hot and cold regions in the North American desert?A) As a desert, the area is arid because of evaporation, extreme temperatures, winds, localized storms, and sun-beaten land.B) Differences of latitude, elevation, climate, topography, vegetation, soil, and human use have divided the desert.C) South of this basin is the Mojave Desert, which is the hot region of the North American Desert.D) This area covers almost all of Nevada, western Utah, and sections of the neighboring states. People take cars and other road vehicles for granted today. However, the idea of such vehicles was unheard of about 500 years ago. Then, in 1478, the artist and inventor Leonardo da Vinci designed a self-propelled vehicle. His drawing showed a boxy, open-topped wooden machine with three wheels.
