Please be specific about the kind of help you want.  Ideally you'd do all the work you can and then stop and ask questions whose answers might help you move forward again.  Graph the function f(x)=2x+4.  This is the equation of a straight line with slope 2 and y-intercept 4.  What help do you need in doing this?  What help do you need beyond this?

select the correct answer and show your work so what property is illustrated by 18 x 0=0 is it a. zero property b. property of o
juin [17]
It is a, the zero property.  It is so since you are multiplying zero to get an answer of zero.
I will try to elaborate.

The "Zero Product Property" says that:

If   a × b = 0   then   a = 0   or   b = 0   
(or both a=0 and b=0)

18 x 0 = 0

Let's say that 18 = a and 0 = b.  By the converse of the statement, it states that if a or b is zero, then it must be the zero property.  Since b is in fact, zero, then we can conclude that it is, in fact, the zero property.

A car was valued at $44,000 in the year 1993. The value depreciates to $15,000 by year 2002.
almond37 [142]

Answer:

The car will have lost it's total value by 2007.

Step-by-step explanation:

If initially the car was valued at 44,000$, and after 9 years it's value dropped to 15,000$, we can say that the car's value dropped in 29,000$. If we suppose that the drop is the same every year, we can say that it was of 3,222,2$ by each year.

This amount of money is the 7,3% of the initial value of the car (I multiplied 3,222,2 x 100 : 44,000).

a) The annual rate of change was of 7,3%.

b) There are 14 years between 1993 and 2007. If we multiply 7,3% by 14, we get that the car lost 102,2% of it's initial value.
