Answer:
-8b - 5k + 9
Step-by-step explanation:
=(-4b + 15 - 7k) - (6 + 4b - 2k)
Taking away the brackets
=-4b + 15 - 7k - 6 - 4b + 2k
collecting like terms
=-4b - 4b - 7k + 2k + 15 - 6
= -8b - 5k + 11

From the question we are told that:
Car worth 
Car Loan
Bank account 
Savings account 
Credit card
Generally Net worth is the value of the assets a person or corporation owns, minus the liabilities they owe.
Therefore


Answer:
C. Altitude
Step-by-step explanation:
A prism is a polyhedron, with two parallel faces called bases.
Answer: dr/dt = 9/(24pi) cm per minute
9/(24pi) is approximately equal to 0.119366
=============================================
Work Shown:
Given info
dS/dt = 18 cm^2/min is the rate of change of the surface area
r = 6 cm is the radius, from the fact that the diameter is 12 cm
--------
Use the surface area equation given, apply the derivative, plug in the given values and then isolate dr/dt which represents the rate of change for the radius
S = 4*pi*r^2
dS/dt = 2*4*pi*r*dr/dt
dS/dt = 8*pi*r*dr/dt
18 = 8*pi*6*dr/dt
18 = 48*pi*dr/dt
48pi*dr/dt = 18
dr/dt = 18/(48pi)
dr/dt = (9*2)/(24*2pi)
dr/dt = 9/(24pi)
The units are cm per minute, which can be written as cm/min.
