Summer is thinking about buying a car for $45,000. The table below shows the projected value of two different cars for three years. Number of cars: 1 2 3
Car 1 (value in dollars): 40,000 36,450 32,805
Car 2 (value in dollars): 42,000 39,000 36,000

Part A: What type of function, linear or exponential, can be used to describe the value of each of the cars after a fixed number of years? Explain your answer

Part B: Write one function for each car to describe the value of the of the car f(x), in dollars, after x years.

Part C: Summer wants to purchase a car that would have the greatest in 13 years. Will there be any significant difference in the value of either car after 13 years? Explain and show the value of each car after 13 years.

step-by-step explanation:

i used the pitagoras theoreme

the answer is 62.8 cubic units

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
