Base on your question were the are proofs that is given are this are: CB bisects BD, DE bisects EC, CB=DE. So answer your question you must understand first your given statements and realize that CBD and DEC are both right triangles because they are a perpendicular segment so i conclude that the answer should be CBD=DEC because they are both right angles
How many 6/14 of a foot can you make out of 49/14 feet of rope?
Step-by-step explanation:
Suppose that the weight (in pounds) of an airplane is a linear function of the amount of fuel (in gallons) in its tank. When carrying 15 gallons of fuel, the airplane weighs 2187 pounds. When carrying 35 gallons of fuel, it weighs 2303 pounds. How much does the airplane weigh if it is carrying 50 gallons of fuel?
----
You have two points relating fuel and weight.
(15,2187) and (35,2303)
------------
slope = (2303-2187)/(35-15) = 5.8
----
intercept = ?
2187 = 5.8*15 + b
b = 2100
-------
Equation:
f(x) = 5.8x + 2100
---
f(50) = 2390 lbs.
