Answer:
The solution is: x = -1, and y = 8/3
Step-by-step explanation:
Notice that the system of equations can be easily solved via the "elimination" method, by subtracting term by term one equation from the other. Doing such will remove completely the term in "y" (since the terms in "y" are exactly equal in both equations), and leave only an equation containing "x", for which the value can be solved:
Now we use this x-value in either equation to solve for y:
Answer:
A. I only
Step-by-step explanation:
We need to start off by <u>taking perfect squares out of these square roots.</u>
Begin with the numerator. It looks like we can take 4 out of the radical:<u />
Now we have
Looks like those s can cancel!
= 2
Plug those answers into your calculator. II and III don't equal 2, but I does. This makes sense when we consider the rule that if you're dividing two radicals, you can just pull the radical over the whole expression!
The answer is <u>A. I only.</u>
