Which equation is y=-3x2 – 12x – 2 rewritten in vertex form?
y=-3(x + 2)2 + 10
y=-3(x - 2)2 + 10
y=-3(x + 2)2 – 14
y=-3(x - 2)2 - 2

the answer is the first one

Step-by-step explanation:

the easiest way is to look at the constant. negitive three multiplies with 2 to get -6. Then it is multiplied with 2 again to get -12. Then add 10 to get -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
