Straight line depreciation, the value of the car is given by the following equation, where V is the value of the car, and O is the original value of the car, and x is the number of years since buying the car. V=O-2x This equation follows the form of a straight line, that is: y=mx+b
Answer:
a^2 + b^2 = c^2, where c is the hypotenus and a and b are the legs
Step-by-step explanation:
Answer:
each brother received 1,015 marbles cus 2,030 divided by 2 is 1,015.
9x^2 -c =d
add c to each side
9x^2 = c+d
divide by 9
x^2=(c+d)/9
take the square root on each side
x = +- sqrt ((c+d)/9)
simplify
x = +- 1/3 sqrt (c+d)
Answer: 1/3 sqrt (c+d), - 1/3 sqrt (c+d)
The 50 is the error because cents are represented with decimals so it has to be .50
