In this item, I take it that we are to get the cube root of the given expression, -64x6y9. First, we look into the numerical coefficient, this is the product when -4 is multiplied to itself three times as shown below.
-64 = (-4)(-4)(-4)
Then,
x6 = x2 (x2) (x2)
and,
y9 = (y3)(y3)(y3)
If we take the cube root, we consider only one item per product. Thus, the answer is,
-4x²y³
Answer: I believe it should be 
for the final answer and here is how I would solve for this answer.
Step-by-step explanation:
- Subtract 3 from 9 or 3 - 9 which equals: -6.
- Add -6 to 7 or -6 + 7 = 1.
- Divide 1 by 3 and you get .
You get because you can't simplify the fraction into a whole number. And if you need the decimal then you get 0.33333333 or 0.3 repeating.
I hope this helped!
All three of those graphs are functions.
The main thing about a function is for every input in the domain there is exactly one output. That doesn't mean that there has to be a y for every x; the xs with no output, no y, are not in the domain of the function.
So to be a function for every x there needs to be <em>at most one </em>y.
The test for that is called the <em>vertical line test.</em> If you can draw a vertical line (x=constant) through two points of the graph, that graph does not represent a function.
All three of these functions pass the vertical line test. For the first the questionable point is x=-2. A vertical line there passes through the graph at y=0. It doesn't pass through the graph at y=-2 -- the open circle means that interval is open, it doesn't include (-2,-2). So a vertical line passes through at most one point on the graph at all (shown) places, therefore it's a function.
The second one is similar at x=-2. At x=0 there's an open point; the function has no value there. x=0 is not part of the domain. That doesn't mean this isn't a function; it passes the vertical line test, so it's a function.
The third is like the second except now at x=-2 the value's in the right branch, y=-8. Still this passes the vertical line test, so it's a function too.
Answer: all of the above
the perimeter. The perimeter is the total sum of all the edges
