(-4)^2
A negative base raised to an even power gives us a positive so
4^2
4x4=16
The first thing we must do for this case is to define a variable.
We have then:
t: time a customer can stay in a restaurant.
We write now the inequality.
We have then:
Answer:
an inequality to show how long a customer can stay at the restaurant is:

The ordered pair is included in the solution set to the following system is (0,2)
<h3>Set of inequalities</h3>
Given the set of inequalities
y > x2 + 1
y < x2 – x + 1
Equate both expressions to have:
x^2 + 1 = x^2 - x +1
1 = -x + 1
x = 0
Substitute x = 0 into any of the function
y = x^2 + 1
y = 1
This shows that the ordered pair is included in the solution set to the following system is (0,2)
