C because the x coordinate cannot repeat in a function. One x coordinate can go into multiple y coordinates though.
Hope it helps
At first, Michael had 187 channels on his tv. Secondly, he got 9 MORE from the company. So that's 187 + 9 = 196 channels. But then he REMOVED 6 channels from the 196 channels so that's 196 - 6 = 190 channels.
So Michael have 190 channels left.
Hope this helps! :D
Answer:

Step-by-step explanation:

Start by factoring out a 5:

We need to find two integers that have a product of 12, and a sum of -7:
(-3)(-4)=12
-3-4=-7
We can split -7x into -3x and -4x

Factor each half separately:
![5[x(x-3)-4(x-3)]](https://tex.z-dn.net/?f=5%5Bx%28x-3%29-4%28x-3%29%5D)
Since x and -4 are both being multiplied by x-3, we can combine them:

Answer:

And replacing we got:

And we can find the angle with the inverse cosine function and we got:

Step-by-step explanation:
for this case we can use the following identity:

We can begin finding the norm for each vector and we got:


Now we can find the dot product and we got:

And replacing we got:

And we can find the angle with the inverse cosine function and we got:

Answer:
3/2
Step-by-step explanation:
Truthfully, you only need two points for a linear equation, so I will only use two.
(-5, 0)
(-3, 3)
I will use the skeleton method to find the slope
((0) - (3))/((-5) - (-3)) -> -3/-2
The slope is 3/2
