Answer:
Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction.
Answer:

Step-by-step explanation:
You can obtain any two points on the graph of
and use it to draw its graph.
When x=0, 
So you plot (0,2)
When x=1, 
You again plot (1,-71).
With a straight edge you can now draw a straight line through the two points.

Answer:
3=-3
A radical is a mathematical symbol used to represent the root of a number. Here’s a quick example: the phrase “the square root of 81” is represented by the radical expression . (In the case of square roots, this expression is commonly shortened to —notice the absence of the small “2.”) When we find we are finding the non-negative number r such that , which is 9.
While square roots are probably the most common radical, we can also find the third root, the fifth root, the 10th root, or really any other nth root of a number. The nth root of a number can be represented by the radical expression.
Radicals and exponents are inverse operations. For example, we know that 92 = 81 and = 9. This property can be generalized to all radicals and exponents as well: for any number, x, raised to an exponent n to produce the number y, the nth root of y is x.
125 = 5^3 = 25 * 5

The simplification you are trying to do involves finding the prime factorization of a number. Since 125 is not divisible by 2, move on to 3. 125 is also not divisible by 3, so move on to 5. Then 125/5 = 25, and 25/5 = 5, so 125 = 5^3. The prime factorization of 125 is 5^3.
X-13y is the answer to that equation
