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

A line has a slope of 11 and passes through the point (2,4). ​ PLSS HELPP I NEED IT
Ivenika [448]

Answer:

y = 11x - 18

Step-by-step explanation:

Use the equation y = mx + b

m (the slope) = 11

x (the x-coordinate) = 2

y (the y-coordinate) = 4

Plug it in for our original equation:

4 = 11*2 + b

4 = 22 + b

4 - 22 = b

b = -18

Therefore, the answer is y = 11x - 18. The tricks to these problems are usually in the same format, when you are given the slope and a point it passes through, just plug in the slope and the x and y, and solve for b. Hope this helps!
