Answer:
(a) If r is any rational number and s is any irrational number, then r/s is rational
(b) The statement is false when r is 0
Step-by-step explanation:
Given
rational number
irrational number
irrational number
Solving (a): The negation
To get the negation of a statement, we only need to negate the end result
In other words, the number type of r and s will remain the same, but r/s will be negated.
So, the negation is:
rational number
irrational number
rational number
Solving (b): When r/s is irrational is false
Given that:
irrational number
Set r to 0
So:

-- rational
<em>Hence, the statement is false when r is 0</em>
Answer:
+
4
Step-by-step explanation:
The value of price (p) at a point of equilibrium is 13.4. Then the correct option is C.
<h3>What is the linear system?</h3>
A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
The equation of the demand (D) and supply (S) is given below.

Where p is price.
At equilibrium, we have
D = S
Then

A point doesn't have a slope. A line has. You need to find the slope of the line that these 2 points are on. The slope is
(the difference of the 'y' values) divided by (the difference of the 'x' values)
That appears to be zero. It's a horizontal line.
