For this case we have the following system of two equations with two unknowns:
We want to know if the point is the solution of the system:
We replace:
, meets the first equation.
does not comply with the second equation.
Therefore, it is not system solution.
Answer:
The point is not system solution
Answer:
A'(2,5)
Step-by-step explanation:
The position of point A is at (-2,5), and when you reflect it over the y-axis, you just have to switch the signs of the x-coordinate value.
Its the fourth option, as, sin^2A + cos^2A = 1
so, sin^2A = 1 - cos^2A
Answer:
x = 42°
Step-by-step explanation:
You can mark the opposite angle from 96° as 96° and the 2 other unknowns as y.
96 • 2 + 2y = 360
168 = 2y
y = 84
x is half of y.
84 ÷ 2 = 42
