Answer:
Step-by-step explanation:
First the solution to the equation
-4y = x - 18 Divide by - 4. Watch your signs.
-4y / -4 = x/-4 + 18/-4 Do the division. Notice the 18 needs to be divided by - 4 as well as the other two terms.
y = (-1/4)x - 4.5
Second the graph. See below.
Your original equation is what was graphed.
Third: The table with the points added to the graph.
Sample Calculation
x = 10
-4y = 10 - 18
-4y = - 8
y = -8/-4
y = 2
Point (10,2)
The graph on the right includes the table with 3 points plotted.
Answer:
Step-by-step explanation:
we know that
The formula to calculate the depreciated value is equal to
where
V is the depreciated value
P is the original value
r is the rate of depreciation in decimal
x is Number of Time Periods
in this problem we have
substitute the values and solve for x
Apply log both sides
