Answer:
Rate of Change/Slope = -20
Equation: y= -20x +100
Step-by-step explanation:
A. We know the rate of change is also known as the slope. If we used the slope formula to find the slope we can find the Rate of Change.
B. Since we know the slope and 1 point on the graph we can substitute them in for 'b'
(0,100)
(100)=-20(0) + b
b = 100
Since we know the slope and the b value we can write the equation:\
y = -20x +100
Step-by-step explanation:
From the given scenario above, the value of the car after n years is given by the equation,
V(n) = V₁(1 - d)^n
Where V(n) is the value after n years, V₁ is the original value, d is the depreciation rate and n is the number of years. Substituting the known values,
V(n) = ($25,750)(1 - 0.2)^5
= $8,437.76
Thus, the answer is the second choice.
Answer: -5
Step-by-step explanation:
627 is the answer because I just added 229 and 398 because it only gives us those two numbers that are useful
