Answer: 45,000.
Step-by-step explanation:
The equation of inverse variation is given by:-
, where k is the constant of proportionality.
Given: After owning the car for 3 years, its value is $15,000. After owning the car for 5 years, its value is $9,000.
Here,
Then,
or [answer is same in both cases.]
Hence, the constant of proportionality in this inverse variation is 45,000.
Answer:
20 square inches
Step-by-step explanation:
Set width of sign to x.
Set length of sign to y.
5x=y
2(x+y)=24 inches
2(x+5x)=24 inches
12x=24 inches
width = 2 inches
length = 10 inches
Area = 20 square inches

Answer:
43 feet
Step-by-step explanation:
How far is referring to the distance between the two numbers given.
In general, the distance between two numbers, a and b,
is given by |b-a| .
You have that you are finding the distance between -45.5 ft and -88.5 ft.
So the distance between those numbers is given by:
|-45.5-(-88.5)|
|-45.5+88.5|
|88.5-45.5|
|43.0|
|43|
43 (Since the number inside the | | has a distance of 43 from 0)
The distance between -45.5 ft and -88.5 ft is 43 ft.

Answer:
y -4 = 4(x -3)
Step-by-step explanation:
The slope is found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (7 -3)/5 -4) = 4/1 = 4
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
Using the first given point, the equation is ...
y -4 = 4(x -3)
