Pete and winnie visit star cafe every day and they pay for the items using a gift card. the amount, y dollars, on winnie's gift card after x days is given by the equation y=100-19x. the graph shows the amount on pete's gift card over x days. a.) write an equation for the amount on pete's gift card. b.) using your answer in a.) whose gift card had a higher initial amount?

a.) Write an equation for the amount on Pete's gift card.

y = 80 - 10x

b.) using your answer in a.) whose gift card had a higher initial amount?

Winnie's gift card had a higher initial amount.

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

i think asking google will you get the answer to that question
