Answer: First let’s find x.

A straight line adds up to 180 degrees. So wen know that X and the 81 degree angle should add up to 180, so x+81=180 is our equation. Let’s solve.

Subtract 81 from 180

You get x=99 degrees.

Let’s now find Y.

We know because of the alternate interior angles property that x will have to equal 3y-9. We already know x is 99. Let’s set up an equation. 3y-9=99 let’s add our 9. We get 108. Divide by 3. We get y=36.

If the rate of inflation is 3.4%per year, the future price pt(in dollars) of a certain item can be modeled by the following expo
Doss [256]

Answer:

The current price is $3000 and price after 9 years from today is $4054.

Step-by-step explanation:

The future price pt(in dollars) of a certain item can be modeled by the following exponential function

p(t)=3000(1.034)^t

where, t is the number of years from today.

Substitute t=0 to find the current price.

p(0)=3000(1.034)^0=3000

Therefore the current price is $3000.

Substitute t=9 to find the price after 9 years from today.

p(9)=3000(1.034)^9

p(9)=3000(1.35109177087)

p(9)=4053.27531261

p(9)\approx 4054

Therefore the price after 9 years from today is $4054.
