Answer:
135 = x
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to and exterior angle that is supplementary to the third interior angles
88 + 47 = x
135 = x
For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have the following equation:

We manipulate algebraically to write the equation of the slope-intersection form:

We check if the given point belongs to the equation:

The point does not belong to the equation.

Answer: $44,518
Step-by-step explanation:
Using the formula:
PV = P(
)
PV = present value
P = Principal
r = rate
n = number of periods
From the question :
PV = ?
P = $10,000
r = 0.04
n = 5
Substituting into the formula , we have
PV = 10,000 (
)
PV = 10,000 (
)
PV = 10,000 ( 
PV = 10,000 ( 4.451822331 )
PV = 44518.22331
Therefore :
PV≈ $ 44,518
