Step-by-step explanation:
There are multiple answers for this, here's one: EC/BC = DE/AB
Answer:
Step-by-step explanation:
Let the x-axis be the time (in years) and the y-axis the value of the fax machine (in dollars).
We know that the initial value of the fax machine is $100; in other words, when the time is zero years, the value is $100, or as an ordered pair (0, 100). We also know that after 1 year the value decreases to $80, so (1, 80).
Now we can find the slope of the line passing through those two points using the slope formula
where
is the slope
are the coordinates of the first point
are the coordinates of the second point
Replacing values:
Now, to complete our model we are using the point slope formula
where
is the slope
are the coordinates of the first point
Replacing values:
We can conclude that the correct linear depreciation model is
Answer:
Simplifying
3k(k + 10) = 0
Reorder the terms:
3k(10 + k) = 0
(10 * 3k + k * 3k) = 0
(30k + 3k2) = 0
Solving
30k + 3k2 = 0
Solving for variable 'k'.
Factor out the Greatest Common Factor (GCF), '3k'.
3k(10 + k) = 0
Ignore the factor 3.
Subproblem 1
Set the factor 'k' equal to zero and attempt to solve:
Simplifying
k = 0
Solving
k = 0
Move all terms containing k to the left, all other terms to the right.
Simplifying
k = 0
Subproblem 2
Set the factor '(10 + k)' equal to zero and attempt to solve:
Simplifying
10 + k = 0
Solving
10 + k = 0
Move all terms containing k to the left, all other terms to the right.
Add '-10' to each side of the equation.
10 + -10 + k = 0 + -10
Combine like terms: 10 + -10 = 0
0 + k = 0 + -10
k = 0 + -10
Combine like terms: 0 + -10 = -10
k = -10
Simplifying
k = -10
Let's solve for h
hx = 0.5x - 9
Step 1: Divide both sides by x.
hx/x = 0.5x - 9/ x
Answer = h = 0.5x - 9/ x
