Sam purchased a new car for $17,930. the value of the car depreciated by 19% per year. when he trades the car in after x years, the car is worth no more than $1,900.

fill in the values of a, b, and c to complete the exponential inequality of the form a(b)x ≤ c that can be used to determine the number of years after which the car is worth no more than $1,900.

Step-by-step explanation:

The decay factor for 19% per year depreciation is 1 - 0.19 = 0.81, so the exponential expression for the value of the car after x years is ...

  17930·0.81^x

We want to write an inequality that compares this value to $1900, so that inequality will be ...

  17930·0.81^x ≤ 1900

Comparing this to the given form, we see that ...

  a = 17,930

  b = 0.81

  c = 1,900

The solution is x ≥ 10.6521.

Statement 1 : True

Statement 2: False

Statement 3: False

Statement 4:True

Statement 5:False

Statement 6:True

Step-by-step explanation:

Given :

To Find: Which statements about the system are true?

Solution:

Slope intercept form:

where m is the slope

Convert the given equations in slope intercept form

Equation 1:

 --A

On comparing with general form

Slope = m =

Equation 2:

 --B

On comparing with general form

Slope = m = 1

Substitute the value of x form B in A

Substitute the value of y in B to get value of x

Thus the solution is (0,5)

Thus The system has one solution.

So, Statement 1 is true

Since the slopes of the given lines are not same so the lines are not parallel

Thus the statement 2 is false.

Slope of line 1 is and slope of line 2 is 1

Since the slopes are not same

So, statement 3 is false.

Equation 1:

To find y intercept substitute x =0

Equation 2:

To find y intercept substitute x =0

So,statement 4 is true Both lines have the same y-intercept.

Statement 5: The equations graph the same line.

Statement 5 is false (refer the attached graph)

Statement 6 is true The solution is the intersection of the 2 lines (refer the attached graph)
