1 answer:

5 0

Here how about this To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points

If x is a rational number and y=2/3, which statement describess the sum of x and y?

Harman [31]

Answer:

The answer is: The sum of x and y is a rational number.

Step-by-step explanation:

x is a rational number (any).

$\frac{2}{3}$ is a rational number too.

So, the sum of x and y will also be a rational number.

Simplify.

Sidana [21]

<h3>Answer: $3\sqrt{7}$ </h3>

3*sqrt(7)

3 times the square root of 7

====================================================

Explanation:

I'm assuming the V stands for square root. You can write sqrt(63).

$\sqrt{63} = \sqrt{9*7}\\\\\sqrt{63} = \sqrt{9}*\sqrt{7}\\\\\sqrt{63} = 3\sqrt{7}$

The idea is to factor 63 in such a way that one factor is the largest perfect square possible, that way we can pull the root apart to simplify as shown above. The rule I used for the second step is $\sqrt{x*y} = \sqrt{x}*\sqrt{y}$

VARVARA [1.3K]

Answer:

283 square inches of wrapping paper.

Step-by-step explanation:

You have to find surface are to have enough wrapping paper. Each plate is 0.5 so multiply that by 8 to get the height of the whole piece. 2pie(5)^2 + 2pie(5)(4)=283
