What is the domain and range for this? please

First one:

Domain: 7 ≤ x ≤ 12

Range: 72 ≤ y ≤ 91

Second one:

Domain: -8 ≤ x 8

Range: -2 ≤ y ≤ 6

Step-by-step explanation:

Domain refers to the values of x and range refers to the values of y

28

step-by-step explanation:

8+8+6+6

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
