3. A newspaper started an online version of its paper 14 years ago. In a recent presentation to stockholders, the lead marketing executive stated, “The revenues for online ads are more
than double that of the revenues for printed ads."
A. Use the graph below to justify the lead executive's statement.
B. Determine the approximate year that the two ad revenues were equal.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
