Simple. Substitue "1.3" for x in the given equation y = 2x + 3.
2x + 3 = y
2 * 1.3 + 3 = y
2.6 + 3 = y
5.6 = y
The solution to the equation with the replacement set {1.3} for x is {5.6} = y.
I hope you understand how to solve the equation! :)
Answer:
Perpendicular.
Step-by-step explanation:
Since x is postive in one equation and negative in the other, it is an indicator that both x's go in different directions.

Answer:
Sine will be equal in Quadrants I and II while cosine is equal in Quadrants I and IV
Step-by-step explanation:
Look on your unit circle to find the quadrant, then add or subtract from either 360 or 180 depending on which quadrant you are in.
