Answer:
y=2x+8
Step-by-step explanation:
Alright so, to find the equation, we need to find the slope first. We can do that by turning the input and output into coordinates.
(1,10) and (2,12)
To find the slope, we do:
Which equals to 2
So right now we can say that the equation is:
y=2x+b
In order to find b, the constant, we just need to plug in the y values and x value of a coordinate:
10=2(1)+b
10=2+b
8=b
So now we can say that the equation is:
y=2x+8
Answer:
Step-by-step explanation:
You might find this easier if you change h(x) to y. It might look more familiar.
you are given 1 point and that is (-1,1). What that means is when x = -1,
y = 1
You have written this as though y is linear. It is not. The power is 1/3, not 1.
Let us try B which is what I think the answer is.
y = (x + 2)^(1/3)
Put x = -1 on the right hand side.
y = (-1 + 2)^(1/3)
y = (1)^(1/3)
The cube root of 1 is 1.
So the answer is
y = (x + 2)^(1/3)

Answer:
Option D.The decrease in the value of the car, which is 8%
Step-by-step explanation:
we have a exponential function of the form
where
y is the value of the car
x is the time in years
a is the initial value
b is the base
r is the rate of decrease
b=1+r
In this problem we have
a=$24,000 initial value of the car
b=0.92
so
0.92=1+r
r=0.92-1=-0.08=-8%-----> is negative because is a rate of decrease
