Question
Find the solution of the system of equations.
Hint:
The expansion of the identity . A polynomial of degree has at most two real solutions.
We are asked to solve the set of equation.
The correct answer is: We are asked to solve the set of equation.
Step 1 of 3
The LHS of the given set of equation is the same. Hence, equate them to eliminate a variable. Thus, we get:
We factorized seven out of the equation to simplify it.
step 2 of 3
Now, solve the simplified equation:
Here, the multiplicity of the solution is two.
Step 3 of 3
Substitute the found value of in any of the equation, to find the value of Y.
when x = 1,
Thus, the solution is (1,19).
The multiplicity of a solution is the number of times that value appears to be a solution of an equation.

We could possible draw numerous trends for a line. But the main purpose is to describe the pattern of the values from the line. So, it is necessary to choose the best fit for the set of values.

Like sharks, orcas have smooth bodies that can speed through the water, and lots of sharp teeth. But these is are major difference sharks are wish, while orcas are mammals! Like most fish, sharks by lay eggs: But orca babies are born live and drink milk from their mothers. Another difference is that orcas have Sony skeletons, but sharks have no bones at all-only casttly.

For each of the following sets of bivariate data with variables x and y:
Draw a scatter plot by hand. Decide whether y generally increases or decreases as x increases.
If the two variables increase and decrease together, then they are directly proportional and have a positive slope.
