Answer:

It will always be the case when A and B are opposites

Step-by-step explanation:

sin(x) = -sin(-x) so ...

sin(A -A) = (A -A) = sin(A) -sin(A) = 0

That is, the given expression is true when B=-A.

vagabundo [1.1K]

Answer:

To determine if the point is a solution, substitute the x value into the right side of the inequality and compare the result with the y value of the point.

- x + 2 = - 1 + 2 = 1

Now - 3 < 1

Thus (1, - 3) is not a solution
