Volumes scale as the cube of a corresponding dimension. Therefore, if the radius of a sphere is doubled (r becomes 2r), the surface area becomes 2 squared, or 4 times the original surface area. The volume would become 2 cubed, or 8 times the original volume.
Answer:
B is 5/8
Step-by-step explanation:
Note: 4/8 = 1/2 and 6/8 = 3/4
The lines intersect at a different point than before the changes.
Because the orange line will keep the same slope, the orange line will always cross the blue line, but the point where it intersects will change depending on the new value of the y-intercept.

Answer:
4x - 3(12x + 4) = -6
Step-by-step explanation:
Solving the first equation for y, you have ...
12x +4 = y . . . . add y+4 to both sides
Replacing y with (12x+4) in the second equation gives ...
4x -3(12x +4) = -6 . . . . matches the second choice
