For the first 3 you just have to divide (forget about the square root for now) and then reduce its result by finding two numbers (one of them have to be able to be squared rotted) that multiplied gives the fist result. Then you just have to square root one of the numbers and leave the other one as it is.
For the last 4; you cannot have radicals in the denominator, so you have to multiply both top and bottom by the square root, after that you just reduce.
Hope you understand, if you have any questions please let me know.
Answer:
(0, -3)
Step-by-step explanation:
Here we'll rewrite x^2+y^2+6y-72=0 using "completing the square."
Rearranging x^2+y^2+6y-72=0, we get x^2 + y^2 + 6y = 72.
x^2 is already a perfect square. Focus on rewriting y^2 + 6y as the square of a binomial: y^2 + 6y becomes a perfect square if we add 9 and then subtract 9:
x^2 + y^2 + 6y + 9 - 9 = 72:
x^2 + (y + 3)^2 = 81
Comparing this to the standard equation of a circle with center at (h, k) and radius r,
(x - h)^2 + (y - k)^2 = r^2. Then h = 0, k = -3 and r = 9.
The center of the circle is (h, k), or (0, -3).

Answer:</h2>
First: info on point-slope form.
- Formula: <em>y - y₁ = m(x - x₁)</em>
We need to find the slope of the line first.
Slope:
Now we can complete the point-slope equation of the line.
*These equations are equivalent.
Answer:
Trombolysis
Step-by-step explanation:
Etymology is the study of the history of the words, the origin of them. In medical terminology roots, suffices and prefixes in Latin and ancient greek are commonly used to describe symptoms, deceases, etc.
Prefixes don't require further modification to be added to a word root because the prefix normally ends in a vowel or vowel sound, suffixes are attached to the end of a word root to add meaning such as condition, disease process, or procedure.
Considering this we look for the Latin of destruction, desintegration, "lyse", and then modify it as a termination suffix "-is", obtaining the termination "-lysis", and finally, we unify both words into one:
Trombolysis
I hope you find this information useful and interesting! Good luck!
