X + y = 5 . . . . . . . . (1)
y = 1/2x + 2 . . . . . .(2)
putting (2) into (1), we have,
x + 1/2x + 2 = 5
3/2x = 5 - 2 = 3
x = (3 x 2)/ 3 = 2
y = 1/2(2) + 2 = 1 + 2 = 3
Answer: the third option.

Exponential functions increase rapidly how would you describe the behavior of an inverse function to that
Nady [450]

The exponential functions have the form f(x) = bˣ where b> 0 and b≠0.

Step-by-step explanation:

Exponential function is given in the form of f(x)= bˣ

When working with the inverse of a function, the inputs (x) and outputs(y) exchange their places and the inverse will be the reflection over the identity line y= x

The example of exponential function is the growth of bacteria. If you start with 1 bacterium and it doubles every hour, you will have 2x bacteria after x hours and it is written as f(x) = 2x.  

The exponential function will be bigger than the polynomial and it always have the positive number other than 1 as the base.

The instantaneous rate of change of a quantity with respect to time is proportional to the quantity by itself.

The value of a car is deprecting at the rate of 12% Find the correct value of car when cost of car was rs 350000
kow [346]

Answer:

The cost of the car is $ RS 308,000.

Step-by-step explanation:

Given that the value of a car is deprecting at the rate of 12%, to find the correct value of car when cost of car was $ RS350,000 last year, the following mathematical calculation must be performed:

100 - 12 = 88

88/100 = 0.88

350,000 x 0.88 = X

308,000 = X

Therefore, the cost of the car is $ RS 308,000.
