Answer:
t ≤ 12
Step-by-step explanation:
Answer:
B. equivalent
Step-by-step explanation:
Our two equations are:


Let's use substitution and plug in the expression
for y in the second equation. That way, we're getting rid of a variable so we can solve for the other:





This means that there are an infinite number of solutions possible for this system - any x value will work. So, the answer is equivalent, because these two equations are essentially the same.
Answer:
V(r) represent the volume of air inside a basketball in cubic units for a given radius r in units
Step-by-step explanation:
we have the function

where
V is the volume of a sphere (dependent variable or output function)
r is the radius of the sphere (independent variable or input variable)
therefore
V(r) represent the volume of air inside a basketball in cubic units for a given radius r in units
Answer:
$102.55
Step-by-step explanation:
70 - 19.95 - (10.50 X 5) + 105 = 102.55
