3x < -6, write the solution set

x <-2

Step-by-step explanation:

Divide both sides by three. x will ALWAYS be less than -2. If you were to graph this, you would have an open dot in the spot of -2, and the line would go to the left, which means the domain is restricted to being less than -2.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
