What is the slope of the line?

Mathematics
1 answer:
Savatey [412]3 years ago
8 0

Answer:

C. -3

Step-by-step explanation:

Start from (-1,4) drop down -6 spots then move over 2 spot to end up at (1,2). This is the same as writing -6/2 which equals -3.

If you start from other point (1,2) you'll have to move up 6 then back -2 to get to (-1,4) which is also -6/2 like above and slope is still -3.

Remember y = mx + b

m is the slope and with above example -6/2 top number is rise which move up/down and bottom number is run which move left/right.

Another way of solving it is:

(y2 - y1) / (x2 - x1)

4 - (-2) / -1 - 1

6 / -2

-3

I really need help find x in this triangle
arsen [322]

Answer:

x = 5

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

72 + 6x + 2 + 17x - 9 = 180

23x + 65 = 180 ( subtract 65 from both sides )

23x = 115 ( divide both sides by 23 )

x = 5

(this is my sister on my acc I'm letting her) True or False? When you use a pulley you use less force to pull up a load.Explain
natta225 [31]

Answer:

True depending on what you are comparing it to.

Step-by-step explanation:

A pulley would help lighten the load that you are trying to pull up, which may make it easier for you to get the load to your designated area. The more complicated it is, usually the more 'lighter' it becomes, or the less force you have to exert.

For example, you will have to give a 100% energy in trying to life a heavy box. However, if you use a simple pulley (only one), you may only have to exert 75% more energy, for the weight is significantly lower.

Alright, lets get started.

Please take a look to the diagram I have attached.

The base side is ON

The terminal side is MN.

We could say angle MNO as angle N.

We could day it as angle ONM also.

So, the answer is ∠ N and ∠ONM.   :  Answer
