A relation of a function is only if it relates each element in its domain to only one element in the range
<h2>
Hello!</h2>
The answer is: True.
<h2>Why?</h2>
A counterexample is a way that we can prove that something is not true about a mathematical equation or expression, it's also considered as an exception to a rule.
So:

Then, evaluating we have:

Hence, we can see that the equation is not fulfilled, so, 45° is a counterexample for
and the answer is true.
Have a nice day!

Subtracting 5 from both sides yields

<u>Part</u><u> </u><u>2</u>
When the output, f(x) is 2, we can substitute that in to obtain

Answer:
D
Step-by-step explanation:
This is a 90 degree angle
90-35=55
X=11
35+5x=90
-35. -35
5x=55
Divide both sides by 5
X=11
Answer:
3/10
Step-by-step explanation:
There are 10 students
5 of them voted either Los Angeles or New York
That means ignore (screw) the other 5 people
If 2/10 students chose Los Angeles,
that is 2/5 because the others didn't choose those cities that are part of the equation (nobody asked about the other people)
So if 5 people chose two groups of cities, and two people chose one city, that meant 3 chose the other
3/10 (remember its out of all of them) Students Voted for New York
Hope this helps :)
