Answer:
The number of miles driven after
Step-by-step explanation:
is how much they charge flat out
2 dollars for each mile after the first
x-1 tells you how many miles they have driven after the first
Answer:
Actual value after 5 years is £1344 more than John's value.
Step-by-step explanation:
Johns estimate:-
V = k/t (inverse proportionality) where V = value of the car and t = it's age.
When t = 2, V = £12,000:-
12,000 = k/2 giving k = 24,000
Therefore the value at 5 years of age, according to John's proposition is
V = 24,000 / 5 = £4,800
The actual value using the given depreciation is
12000(1 - 0.2)^3 = £6144
Difference is £1344
They way to find the y-intercept from two points is to first find the slope, which can be derived from the formula 
.
Then, you can plug in one of the two points 
or 
into the formula y=mx+b to solve for b, which is your y-intercept.
Answer:
c = 289
Step-by-step explanation:
Given
x² + 34x
To complete the square
add ( half the coefficient of the x- term )² to x² + 34x
= x² + 2(17)x + 17²
= x² + 34x + 289 ( with c = 289 )
= (x + 17)² ← perfect square
