Answer:
Step-by-step explanation:
We can plug this into a formula and get

the .9075 comes from 1 - the depreciation value of 9.25% which converts to .0925 in decimal form.
? is what we are trying to solve for.
We can divide both sides by 19,700 and we get

so ? is about 13.
Answer:
x and y = 0
the question looks weird and almost wrong because when you subtract the equations, you are left with nothing
Step-by-step explanation:
Multiply the top equation by 3 to make the -x a -3x instead.
Then do the top equation - the bottom equation
At this point you should be left with x
Answer:
a) y = .70x + 20
-To find this, use the rate as x since it will change based on the number of miles. Since 20 is a flat fee, it can be added at the end as a constant.
b) This graph forms a straight line.
-This is because the answer in a is a linear equation.
c) The slope is .70 and the y-intercept is 20.
-For this one, the y-intercept is always the constant at the end of the equation and the slope is the coefficient of x.
Distribute
10+4x+4+5
Combine like terms
19+4x
Final answer: 4x+19
