<h2>Answer</h2>

x=\sqrt{6}, y=0\\ x=-\sqrt{6} , y=0\\x=\sqrt{5} , y=-1\\x=-\sqrt{5} , y=-1

Or as ordered pairs: (\sqrt{6} ,0),(-\sqrt{6} ,0),(\sqrt{5} ,-1),(-\sqrt{5} ,-1)

<h2>Explanation</h2>

Lets solve our system of equations  step by step

x^2+y^2=6 equation (1)

x^2-y=6 equation (2)

1. Solve for x^2 in equation (2)

x^2-y=6

x^2=6+y equation (3)

2. Replace equation (3) in equation (1) and solve for y

x^2+y^2=6

6+y+y^2=6

y^2+y=0

y(y+1)=0

y=0 or y=-1

3. Replace the values of y in equation (3) and solve for x

- For y=0

x^2=6+y

x^2=6

x=\sqrt{6} or x=-\sqrt{6}

- For y=-1

x^2=6+y

x^2=6-1

x^2=5

x=\sqrt{5} or x=-\sqrt{5}

So, the solutions of our system of equation are:

x=\sqrt{6}, y=0\\ x=-\sqrt{6} , y=0\\x=\sqrt{5} , y=-1\\x=-\sqrt{5} , y=-1

The surface area of this cube is 96 square meters. what is the value of y?
ELEN [110]
The formula for finding the surface area of a cube is A=6y^2 where y is the side length. we know a=96. so we just isolate y.
96/6= 6y^2 / 6
16=y^2
sqrt (16) = sqrt(y^2)
4=y

So y is 4

You roll a number cube twice what is the probability of rolling a 2
Colt1911 [192]

The probability of getting a 5 from the first rolling is 1/6.  The probability of getting an even number  is 1/2 (= 1/6 (for a 2) + 1/6 (for a 4) + 1/6 (for a 6)).  As the two rollings are independent, you can just multiply two probability values to come up with a final answer.  That is, (1/6)·(1/2) = 1/12.

Note that I did not write this. This answer comes from Wyzant. I am only linking this to you so that you'll get the answer quickly.

When looking at the net of a cylinder, what is the relationship between the height of the rectangle and the cylinder?
Nastasia [14]

Volume of a cylinder = πr²h

where,

r is the radius of the cylinder

h is the height of the cylinder

Area of the rectangle = length X breadth

We can consider that a rectangle if rotated will form a cylinder.

In that case, the breath of the rectangle will become the diameter of the cylinder and the length will become the height of the cylinder.
