<h3>Answer: y = -2x+1</h3>

====================================

Explanation:

Use the slope formula to get the slope

m = (y2-y1)/(x2-x1)

m = (-3-1)/(2-0) .. I used the first two points

m = -4/2

m = -2

The slope is m = -2

The y intercept is b = 1 as this is the y coordinate of the point (0,1). The y intercept always happens when x = 0.

Plug the m and b value into y = mx+b to get y = -2x+1

As a check, plug x = 0 into y = -2x+1. You should get y = 1.

Repeat for x = 2 and you should get y = -3

Repeat for x = 4 and you should get y = -7

A 25 kg rock , is raised to the top of a hill 10 m high. What is the PE of the rock ?

$Potential \: \: Energy =(mass) \times (gravity \: acceleration) \times (height) \\$

_________________________________

If gravity acceleration is 10 :

$PE = 25 \times 10 \times 10$

$PE = 2500$

_________________________________

If gravity acceleration is 9.8 :

$PE = 25 \times 9.8 \times 10$

$PE = 25 \times 98$

$PE = 2450$

PLZZZ HELP WILL MAKE BRAINLY

Answer:

Step-by-step explanation:

To divide 364 into two parts in the ratio 15:11, add 15+11 to get 26. Now divide 364 by 26 to get 14. This counters 14 for each part, and we have 26 parts. If each part is x, and x=14, x times 15 will equal 15x=210, so the first number is 210. x times 11 will equal 11x=154, so the second number is 154. 210-154=56, so the first number is 56 bigger than the second.

Suppose the profit a honda dealership makes on the next 5 accords it sells are:564, 1,000, 848, 1,495, 1,348. calculate the stan

stepladder [879]

First we have to find the mean (average)
mean = (564 + 1000 + 848 + 1495 + 1348) / 5 = 5255 / 5 = 1051

now we subtract the mean from every data point, then square it
564 - 1051 = -487......-487^2 = 237169
1000 - 1051 = -51......-51^2 = 2601
848 - 1051 = -203......-203^2 = 41209
1495 - 1051 = 444......444^2 = 197136
1348 - 1051 = 297......297^2 = 88209

now find the mean of the results.....but know when ur dealing with a sample instead of the whole population, u divide by 1 number less...so instead of dividing by 5, u divide by 4.
(237169 + 2601 + 41209 + 197136 + 88209) / 4 = 566324 / 4 =
141581.....this is called ur variance

now take the square root of the variance and u have ur standard deviation
sqrt (141581) = 376.272 rounds to 376.27 <==

Answer:

x and y

Step-by-step explanation:

Variables are always the numbers that're replaced with a letter. For example, in the equation:

2t+6

t would be the variable.

Hope this helps!! <3 :)
