The unit vector that is in the same direction as v is given by:
<h3>How to find a vector given two points?</h3>
The vector is given by the <u>terminal point subtracted by the initial point,</u> hence:
v = (-17, 4) - (7, -9) = <-24, 13>
<h3>How to find the unit version of a vector?</h3>
Each coordinate of the vector is <u>divided by it's norm</u>.
For this vector, the norm is given by:
Hence the unit vector is:

To solve this, I'm assuming that the equations both represent angles:
There is a theorem that states that an exterior angle of a triangle is equivalent to the sum of two remote triangles. Knowing this:
11x + 7 = 7x + 14 + 25
11x + 7 = 7x + 39
4x = 32
x = 8
He didn’t multiply the equation by 1/2 in the second part so it threw his whole answer off. Hope this helps
Answer: $300
Step-by-step explanation:
Mr. Calvin earned 
He spent 
on food i.e.
Remaining money = 
So, he saved $300 after expenses
The scale factor is 2
x = 11.5
14/7 = 2
23/x = 2
x = 11.5
