They have the same slope. All three lines are parallel. Any parallel lines have equal slopes.
Answer:
x > -1
Step-by-step explanation:
-3x +3 < 6
-3x < 6 - 3 (subtract 3 from both sides)
-3x < 3 (divide both sides by 3)
-x < 1 (multiply both sides by -1, remember to flip the inequality when multiplying both sides by negative numbers)
x > -1 (answer)
A basketball is the shape of a sphere.
The volume of a sphere is given by

Given that the diameter of the basketball is 10 in., thus the radius is 10 / 2 = 5 in.
Thus, the volume of the basketball is given by

Therefore, The best approximate of the volume of the basketball is
1$ = 100 cents, 1 hour = 60 minutes
$7.80/hour = (7.8*100) cents / (1*60)minutes
= 780 cents/60 minutes
= 13 cents/minute
