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 in the formula

10,000,000
Step-by-step explanation:
you round up, so that makes it 10,000,000
Answer: f(x) = -3x + 4
Step-by-step explanation:
The function is represented by
9x + 3y= 12
This is a linear equation with x as the independent variable. This means that if x is the independent variable, the y is the dependent variable. The values of y depends on the values of x. In order to represent the function, 9x + 3y= 12, we would rearrange the function such that y stands alone on the left hand side of the equation. This becomes
9x + 3y= 12
Subtracting 9x from both sides,
9x -9x + 3y = 12 - 9x
3y = 12-9x
Dividing the lefthand side and right hand side of the equation by 3, it becomes
3y/3 = (12-9x)/3
y= -3x + 4
using function notation,
y = f(x) = -3x + 4
Answer: I can use variables to represent the coordinates of the vertices for a general triangle ABC. then I can calculate the midpoints of the sides in terms of the same variables, and calculate the slope of each midsegment showing that the expression for the slope of a midsegment is the same as the expression for the slope of the third side of the triangle proves that the two are parallel.
Step-by-step explanation: this is word for word btw!
f(x) = 3x + 1
y = 3x + 1
y - 1 = 3x + 1 - 1
<u>y - 1</u> = <u>3x</u>
3 3
¹/₃y - ¹/₃ = x
y = ¹/₃x - ¹/₃
f⁻¹(x) = ¹/₃x - ¹/₃
f⁻¹(10) = ¹/₃(10) - ¹/₃
f⁻¹(10) = 3¹/₃ - ¹/₃
f⁻¹(10) = 3
It is equal too (10, 3).
