The solution is x= 3 and y = 1
Step-by-step explanation:
Given equations are:
From equation 1:
Putting in equation 2:
Dividing both sides by -9
Putting y = 1 in equation 1:
Hence,
The solution is x= 3 and y = 1

Answer:
x power 3(x cube)- 6x -72=0 there it has change to quadratic equation x power 3(x cube)-12x+6x-72=0
Make sure you know how to do these you will be using this for the rest of your mathematical schooling.

Answer:C
because the rest do not have the correct y intercept which is -3
y=mx+b
y=output
m=slope (growth rate)
x=input
b= y intercept
In set theory<span>, the </span>complement of a set A<span> refers to </span>elements<span> not in </span>A<span>. The </span>relative complement<span> of </span>A<span> with respect to a set </span>B<span>, written </span><span>B \ A</span><span>, is the set of elements in </span>B<span> but not in </span>A<span>. When all sets under consideration are considered to be </span>subsets<span> of a given set </span>U<span>, the </span>absolute complement<span> of </span>A<span> is the set of elements in </span>U<span> but not in </span>A<span>.
</span>The empty set<span> is the </span>set<span> containing no elements. In mathematics, and more specifically </span>set<span> theory, the </span>empty set<span> is the unique </span>set<span> having no elements; its size or cardinality (count of elements in a </span>set<span>) is zero.

Roster Form<span>: This method is also known as tabular method. In this method, a set is represented by listing all the elements of the set, the elements being separated by commas and are enclosed within flower brackets { }. Example: A is a set of natural numbers which are less than 6.
</span>
Set-Builder Notation<span>. A shorthand used to write </span>sets<span>, often </span>sets<span> with an infinite number of elements. Note: The </span>set<span> {x : x > 0} is read aloud, "the </span>set<span> of all x such that x is greater than 0." It is read aloud exactly the same way when the colon : is replaced by the vertical line.

Universal set:<span>the set containing all objects or elements and of which all other sets are subsets.</span>
