Answer:
exponential decay because the base is less than one
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
to be a function, there has to be exactly one x for every y. if there is more than one per y, it makes it not a function. so, if there is two of the same number in the x, it's not a function.
Answer:
$42,890
Step-by-step explanation:
The standard form for an exponential equation is

where a is the initial amount value and b is the growth rate or decay rate and t is the time in years. Since we are dealing with money amounts AND this is a decay problem, we can rewrite accordingly:

where A(t) is the amount after the depreciation occurs, r is the interest rate in decimal form, and t is the time in years. We know the initial amount (70,000) and the interest rate (.04), but we need to figure out what t is. If the car was bought in 2006 and we want its value in 2018, a total o 12 years has gone by. Therefore, our equation becomes:
or, after some simplification:

First rais .96 to the 12th power to get
A(t) = 70,000(.6127097573)
and then multiply.
A(t) = $42,890
To simplify the equation, we have y = 
<h3>How to simply the expression</h3>
Given the expression
y-8 = 3/4x [x-(-6)]
First, expand the bracket
= 
Make 'y' the subject of formula
y = 
Thus, to simplify the equation, we have y =
