1.) y= 2/3x
2.)y= -1x + 1
3.)y= 2x + 1
4.)y= -2/3x + 1
The structure of the formula is y = mx + b.
m is the slope.
slope is found by rise over run.
b is the y intercept.
which is found by where the line is on the y axis
Although I am unsure what this question has to do with Mathematics, Joe Bob could simply say "How often do you work out in a week?"
Answer:
D. Drawing 50 names from a hat containing the names of every student in the school.
Answer:
C
Step-by-step explanation:
First, factor the original expression:
As we can see, D is the same as above. Eliminate D.
Go through each of the answer choices.
A:
This is equivalent to what we factored. Eliminate A.
B:
This is again equivalent to what we factored. Eliminate B.
C:
This cannot be simplified and it is not equivalent to what we have previously. C is not the equivalent expression.
Answer:
65.56°
Step-by-step explanation:
We know that if we take dot product of two vectors then it is equal to the product of magnitudes of the vectors and cosine of the angle between them
That is let p and q be any two vectors and A be the angle between them
So, p·q=|p|*|q|*cosA
⇒
Given u=-8i-3j and v=-8i+8j
let A be angle before u and v
therefore, 
⇒
Therefore angle between u and v is 65.56°
