To find the component form, u only need to know how to substitute figures for letters. What do I mean by this?
If initial side is (x1,y1)
Then x1 = -1, and y 1 = 16
If the terminal side is x2, y2
Then x2 =1 and y2 =9
This component from p is x2-x1 y2-y1
In this case <[1-(-1)], (9-16)
Which give us
2,-7
If p = x ,y using Pythagorean’s theorem
2(2) + (-7)(7)
4+49
53
Square root of 53 is
7.28010988928
7.3
I hope this helps you! it's relatively straightforward but if you need more explanations, don't hesitate to ask!
2x+4=7 subtract 4 from both sides
2x=3 divide both sides by 2
x=3/2
x=1.5

and B must be invertible, we have UA=B, since A is invertible. A^-1 exists, by multiplying with A^-1,
we have UA A^-1 =B A^-1. But AA^-1 = I (identity matrix)
and XI=X, for all matrix X, we find UI= B A^-1, and U= B A^-1.</span>
The answer is 0. the additive inverse of a negative number is the same number but positive. to find the sum means to add them together. for example take 2 and -2. 2 is the additive inverse of -2. if you add 2+-2 the answer comes out to 0
