AnsweYou’ve seen two methods for finding the area of ΔABC—using coordinate algebra (by hand) and using geometry software. How are the two methods similar? How are they different? Why might coordinate algebra be important in making and using geometry software?

Answer:
30
Step-by-step explanation:
Exterior angle equals sum of opposite interior angles
3x = 2x + 30
3x - 2x = 30
x = 30
We have to find out the value of the fraction.
<u>Let us assume that:</u>
<u>We can also write it as:</u>
<u>Comparing </u>the given <u>equation</u> with <u>ax² + bx + c = 0,</u> we get:
<u>By quadratic formula:</u>
<u>But </u><u>"</u><u>x"</u><u> cannot be negative. Therefore:</u>
So, the value of the fraction is 1 + √2.
By definition we have to:
A mathematical function is a relationship that is established between two sets, through which each element of the first set is assigned a single element of the second set or none.
The initial set or starting set is also called the domain; the final set or set of arrival, meanwhile, can be called codomain.
We have the following information:
{(-5.2), (-2.5), (0.7), (0.9)}
The data does not represent a function because two different values of the range belong to an element of the domain:
(0.7)
(0.9)
Answer:
The relation is not a function.
