The cost of cookies at store A are shown in the graph. The cost y for x cookies at store B is represented by the equation y=0.30x. Which of the following statements is true?

The relationship between the cost of cookies and the number of cookies is

a proportional relationship.

Correct response:

The function of the given graph for the cost of cookies at store A is found as follows;

The graph is a straight line passing through the origin, therefore, the equation is of the form;

y = m·x

The cost of 2 cookies = $0.5

Therefore;

The cost of 1 cookie at store A = $0.5 ÷ 2 = $0.25

Therefore, the cost of y cookies = 0.25·x

Where;

x = The number of cookies

The equation representing the cost y for x cookies in store B in dollars is given as follows;

y = 0.30·x

Therefore, the cost of 1 cookie at store B = $0.30 × 1 = $0.30

Therefore;

at least i think its

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
