Tell whether the ordered pair is a solution of the system of linear equations.

melamori03 [73]

Answer: No, it is not a solution. It makes the first equation true, but the second equation is false when (x,y) = (16, 1)

To check a possible solution, we replace the variable letters with their actual numbers. The given solution is (x,y) = (16,1) so x = 16 and y = 1 pair up. We'll replace x with 16, and replace y with 1.

Do so with the first equation and simplify

y = (-1/4)*x + 5

1 = (-1/4)*16 + 5

1 = -4 + 5

1 = 1 ... true

And repeat for the second equation

y = (1/6)*x - 2

1 = (1/6)*16 - 2

1 = 2.667 - 2

1 = 0.667 .... false

The equation above is false, so the original equation is false when (x,y) = (16,1). This proves the point is not on the line.

So overall, (16,1) is not a solution to the system.

A new sidewalk will be 4 feet wide 200 feet long and filled to a depth of 3 inches (0.25 foot) with concrete. How many cubic yar

solmaris [256]

0.25 ft equals 0.083 yd (0.25/3 ft per yd)
4 ft equals 1.33 yd
200 ft equals 66.6 yd

0.083 x 1.33 x 66.6 = 7.35 cubic yards

A brand new car costs $18,000, this price depreciates at 25% every year, how much would the car be after 12 years? 20 years?

Snezhnost [94]

Answer:

C(12)=$570.18

C(20)=$57.08

Step-by-step explanation:

Exponential Decay Function

The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

$C(t)=C_o\cdot(1-r)^t$

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The depreciation of goods is often modeled as an exponential function. The new car costs $18,000 and its price depreciates at r=25%= 0.25 every year.

The depreciation model is:

$C(t)=18,000\cdot(1-0.25)^t$

Operating:

$C(t)=18,000\cdot 0.75^t$

At t=12 years, the price will be:

$C(12)=18,000\cdot 0.75^{12}$

C(12)=$570.18

At t=20 years, the price will be:

$C(20)=18,000\cdot 0.75^{20}$

C(20)=$57.08
