Answer:
For a, the machine depreciates 20% of its current value each year. So, It will lose 20% of its value in the first year. Then in the second year, it will lose 20% of THAT value (not of the original value) and so on.
b) Since the machine loses 20% of its value each year, it retains 80% of its value each
Slope = (-3 - 1) / (4 -4) = -4
Answer:
one x-intercept.
Transformation: shift to the right 8 units.
Step-by-step explanation:
The parent function is 
To find the number of x-intercepts, we equate the function to zero.
There is only one x-intercept at t=0.
The transformed function is
This function is obtained shifting the parent function 8 units to the right.
The x-intercept will now be at t=8.
Hence the image function also has one x-intercept.
Answer:
$6.40
Step-by-step explanation:
2.56 / 16 = 0.16
so 16 cents per oz
16 * 40 = 640
Hi Vanessa
3x -1/9 (27) =18
3x - 27/9 =18
3x- 3 =18
Add 3 to both sides
3x-3+3=18+3
3x=21
Divide both sides by 3
3x/3= 21/3
x= 7
The value of x is 7
Now let's check if my answer is correct
To check it we gonna replace x by 7 and 27 for y
(3)(7) -1/9 (27) = 18
21 -1/9 (27)=18
21- 27/9 = 18
21- 3 = 18
18 = 18
The answer is good and I hope its help:0
