Answer:
multiply x through out:
factorise out x²:
take square root on both sides:
The answer is c. Because there inside and opposite
<h2>
Answer:</h2>
A.) Yes. The input and output are both possible.
<h2>Explanation:</h2>
In this problem, a dentist sees patients each day to clean their teeth. So we represent this function as 
where:
x: Represents the number of people who saw the dentist.
g(x): Represents the number of teeth cleaned.
So we are given a point that is solution to our function, which is 
but <em>what does this point represent? </em>This tells us that the dentist saw 20 patients and cleaned 20 teeth, that is, he cleaned an only teeth per patient. So this will make sense under the conditions that make it possible, for example, a volunteer dentist can see more people than a common dentist and it is likely that that volunteer person sees fewer teeth. However, it's very difficult that that dentist finds 20 people with an only tooth each. So this situation is possible, but not realistic in the real world.
Answer:
change in y: 0
change in x: 5
slope: 0
Step-by-step explanation:
Sub these two points from Line E into the gradient formula (you can search this up on the internet) and you would get 0/5
Points: (1,3) and (6,3)
Rise over run
3-3 over 6-1
0/5 and the answer is 0
Generally, when it asks you to find the slope of a horizontal line, its always 0
