So firstly, substitute the values into the expression: $3^3-2*5^2-3*3^3+(-3)^4$

Next, solve the exponents: $27-2*25-3*27+81$

Next, solve the multiplications: $27-50-81+81$

Lastly, combine everything, and your answer will be -23.

Write the exponential equation for this scenario. Mike buys a car for $45,000.00. The cars value depreciates (loses value) at a

gladu [14]

Answer:

$A=45000(0.82)^t$

Step-by-step explanation:

Given data

P= 45,000

rate= 18%

Recall the expression for the compound interest

$A=P(1+r)^t$

Since we are talking of depreciation

$A=P(1-r)^t$

Substitute

$A=45000(1-0.18)^t\\\\A=45000(0.82)^t$

Hence the exponential function is

$A=45000(0.82)^t$

3y=6x+9
y=2x+3
So, the slope is 2, and the y-intercept is 3

Neporo4naja [7]

Answer: y=300-40x

The y-intercept would be 300

The slope would be -40

Step-by-step explanation:

x=number of months

300 is the amount she starts with

Equation can also be written like so; y=-40x+300 just like in y=mx+b (slope intercept) form
