Answer: Point slope form is y-y1=m(x-x1)
Step-by-step explanation:
Here y1=4
x1=-11
m i.e slope=-2
And there you go.

Answer:
The total number of ways to answer = 32
Step-by-step explanation:
A quiz has five questions that can be answered as true or false.
Each question can be answered in two ways.
Lets take each question one by one.
The first question can be answered as true or false that is two ways.
Similarly each question answered in 2 ways.
To get the total number of ways, we have to multiply the number of ways for each question.
Hence the total number of questions =
= 32
Answer:
1.) 7
2.)7
3.)-7
4.)7
5.)7
Step-by-step explanation:
1.) Just count -2 to 5 with your hands
2.) since two negative signs make a addition sign when they are close to each other, you will just add 5 and 2.
3.) Just add 5 and 2 and add the negative sign before the number.
4.)Same as I said in number 2, it stays 7.
5.) Finally, as number 3, it will be -7 but because of the negative signs it will be 7.
Cosine rule
Cosx=(11 ²+8²-(15²))/2(11)(8)
Cosx=(121+64-225)/176
Cosx=-40/176
Cosx=-5/22
X=cos-1 -5/22
X=103.1
