Part A is a rational number, so adding another rational number (1/3) gives a rational result.
Part B is 2/3, so adding 1/3 gives a sum of 1, which is still a rational number.
Part C is 2*pi, which is irrational, and adding 1/3 gives a sum of 2*pi + 1/3, which still cannot be simplified into a rational expression.
Part D is an irrational number, and 1/3 - sqrt(17) also cannot be simplified into a rational number, so this is irrational.

Therefore the correct answers to this are C & D.

A phone company offers two monthly plans. Plan A costs $25 plus an additional $0.09 for each minute of calls. Plan B has no init
Lisa [10]

Using linear functions, it is found that the two plans cost the same for 5000 minutes of calling.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0.

For Plan A, the cost is of $25 plus an additional $0.09 for each minute of calls, hence the y-intercept is b = 25, the slope is of a = 0.09, and the function is:

A(x) = 0.09x + 25

For Plan B, the cost is of $0.14 for each minute of calls, hence the y-intercept is b = 0, the slope is of a = 0.14, and the function is:

B(x) = 0.14x

The plans cost the same for x minutes of calling, considering that:

B(x) = A(x)

0.14x = 0.09x + 25

0.05x = 250

x = \frac{250}{0.05}

x = 5000

The two plans cost the same for 5000 minutes of calling.
