the current value of a new car is 18,000. the car will depreciate 15% per year over the next 5 year. which exponential equation
Arte-miy333 [17]

The exponential equation that models this situation is:

V(t) = 18000(0.85)^t, 0 \leq t \leq 5.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

For this problem, the parameters are:

A(0) = 18000, r = 0.15.

Hence the equation for the value of the car over the next 5 years is:

A(t) = A(0)(1 - r)^t

A(t) = 18000(1 - 0.15)^t

V(t) = 18000(0.85)^t, 0 \leq t \leq 5.

Toms package weights three more pounds then twice the weight of Momos package. Altogether it equals 15 pounds.
Musya8 [376]
1.   T+3>M^2=15
       -3              -3
        T>M^2=12
       divide 2 on both sides
     T>M=6
      T=9 and M=6
T= 9 because you found M and you use the amount you got rid of to solve M to get T <span />

What is the problem 6y+2(3y-5)= -34
lidiya [134]

Answer:

y=−2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6y+2(3y−5)=−34

6y+(2)(3y)+(2)(−5)=−34(Distribute)

6y+6y+−10=−34

(6y+6y)+(−10)=−34(Combine Like Terms)

12y+−10=−34

12y−10=−34

Step 2: Add 10 to both sides.

12y−10+10=−34+10

12y=−24

Step 3: Divide both sides by 12.

\frac{12y}{12} = \frac{-24}{12}

y=−2
