Answer:
5y = 5
Step-by-step explanation:
-2(x -2y) +(2x +y) = -2(-1) +(3) . . . . -2 times [eq2] + [eq1]
-2x +4y +2x +y = 2 +3 . . . . eliminate parentheses
5y = 5 . . . . . . . . collect terms
The hard part of this question is decoding the equation.
![\angle BAC = \arcsin\left( \dfrac{3.1}{4.5} \right)](https://tex.z-dn.net/?f=%5Cangle%20BAC%20%3D%20%5Carcsin%5Cleft%28%20%5Cdfrac%7B3.1%7D%7B4.5%7D%20%5Cright%29)
There's nothing to do but ask the calculator.
![\angle BAC = \arcsin\left( \dfrac{3.1}{4.5} \right) \approx 43.54^\circ](https://tex.z-dn.net/?f=%5Cangle%20BAC%20%3D%20%5Carcsin%5Cleft%28%20%5Cdfrac%7B3.1%7D%7B4.5%7D%20%5Cright%29%20%5Capprox%2043.54%5E%5Ccirc)
Answer: 44°
Answer:
The correct answer by solving with the System of Inequalities is ![-4\leq x](https://tex.z-dn.net/?f=-4%5Cleq%20x%3C4)

It is true if two vectors point in opposite directions. This means their cross product must be zero.
<h3>What is cross product?</h3>
Cross product is a vector product of two vectors in the three dimensional vector space.
In the case when the two vectors point in opposite directions so there cross product should be zero.
Impact on two points:
In the case when the two vectors point in opposite directions so there cross product should be zero.
Like
A*B = [A][B] sin
Here theta is be the angle that lies between them
So,
A*B = [A][B] sin 180
So, A*B = 0
hence, the given statement is true.
