If you shift the linear parent function , f(x)=x, down 7 units

f(x) = x - 7

This is because the b value determines the y intercept, and if you move the function down 7, you are technically subtracting 7 from the current b value which was 0.

step-by-step explanation:

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
