<span>J(–3, 11) and K(1, –3)
Slope = (11 + 3)/(-3 - 1) = 14/-4 = -7/2

Equation
y + 3 = -7/2(x - 1)
2y + 6 = -7x + 7
2y = -7x + 1
7x + 2y = 1 ....This is standard form (Ax  + By = C)

Hope it helps.</span>

Can a 180 degrees angle be a obtuse triangle? ​
Aleksandr [31]

Answer:

Yes and no, I'll explain below

Step-by-step explanation:

An obtuse triangle can have either a 90 degree angle or an 180 degree angle. This reason being said, an obtuse triangle has ONLY one angle that is greater than 90 degrees. But the sum of any given triangle is 180. Hope this helps!

Answer: s = 36

Step-by-step explanation: The key to solving multistep equations is isolating the variable. This is why I first subtracted 14 on each side. This left me with 1/3s=12. Then, to isolate "s" even more, I didvided by 1/3 on each side. This gave me s = 36 as an answer.

To divide by a fraction, use "keep change flip." Keep the first mumber, change division to multiplication, and flip the fraction. I included a picture of me doing this.

If you have any other questions, please feel free to ask :)

Point m is the midpoint of ab¯¯¯¯¯ . am=3x+3, and ab=8x−6. what is the length of am¯¯¯¯¯¯ ?
LuckyWell [14K]
As given m is a midpoint of ab. So am is half of ab.

So we can write

am =  \frac{ab}{2}

As given am = 3x+3 , ab = 8x - 6.

So 3x+3 = \frac{8x - 6}{2}

3x+3 =  \frac{2(4x - 3)}{2}

3x+3 = 4x - 3

3+3 = 4x - 3x&#10;

6 = x

So x = 6.

So length of am = 3x+3 = 3*6 + 3 = 21
