Two different video game rental stores are in the same shopping center. Each store charges a membership fee in addition to a fee for each game rented. The table shows the prices from each store.

Which system of linear equations can be used to represent the fees charged by the two game rental stores?
А
y = 10x + 4
y = 15 x + 3
B
y = 14x
y = 18x
С
y = 4x + 15
y = 3x + 10
D
y = 4x + 10
y = 3x + 15

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)
