Plug in 4 for x.
f(x) = 2x - 10
f(4) = 2(4) - 10
Simplify. Remember to follow PEMDAS. First, multiply, then subtract
f(4) = 8 - 10
f(4) = -2
-2 is your answer for f(4)

Answer:
2141.76 cubic inches
Step-by-step explanation:
Given that it measures 8.8 inches across a properly inflated basketball i.e. the diameter of each basketball is 8.8 inches.
So, the radius of the spherical ball is inches.
Now, a spherical solid has a volume given by .
Hence, volume of air in side each basketball is = cubic inches.
Therefore, the total volume of air inside six balls will be = 6 × 356.96 = 2141.76 cubic inches. (Answer)
Angles B and D are supplementary angles, so if B's angle is 30 degrees, then D's angle at y would be 150, since they have to add to 180.
In short, angle y = 150
