Step-by-step explanation:
Given

The question has missing details; as what's required is not stated.
However, since it is a linear equation, possible questions could be
1. Determine the slope
2. Determine the D-intercept
3. Calculate the amount in dollars for (say) 5 miles
An equation is represented as:

Where


By comparing:
to 
and 
This means that the slope is 0.3 and the d intercept is 25
To get the amount for 5 miles, we substitute 5 for x in 



<em>The cost of 5 miles is $26</em>
Make use of the above explanation to solve the question
Answer:
x² - 20 = 0
Using the quadratic formula

a = 1 b = 0 c = -20
So we have

The answer to your question is 102
Answer:
<h2>2.14367............. is a irrational number.</h2>
When taking square roots, you can't take square roots of negative roots of negative numbers. So, what will work for the domain of u(x) is what makes u(x) zero or more. We can make an inequality for that.
u(x) ≥ 0.

9x + 27 ≥ 0 by squaring both sides
9x ≥ -27
x ≥ -3
So the domain of the function is when x ≥ -3 is true.
