Explain how to use your number line to find the opposite of the opposite of -6

1 answer:

5 0

You would add 12 to the number line because it would make it the opposite of -6 which is 6 then you go 6-12(MAKE SURE IN THAT ORDER) which would give you the opposite of 6 which is -6 so to show this draw a line from -6 to 6 then above that a line from 6 to -6

Estimate the difference of the decimals below by rounding to the nearest whole number. 23.827

iragen [17]

Step-by-step explanation:

The key rule is: to round up the number one digit to the left has to be the number 5 or more, else it rounds down.

23.827 rounds up because the 8 is more than 5.

1.218 rounds down because 2 is less than 5.

24-1= 23

Find the distance between the two points in simplest radical form.<br> (7,2) and (-1, -3)

Paul [167]

Answer:

The answer is

<h2> $\sqrt{89} \: \: \: \: units \\$ </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x_1 - x_2})^{2} + ({y_1 - y_2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(7,2) and (-1, -3)

The distance between them is

$d = \sqrt{( {7 + 1})^{2} + ({2 + 3})^{2} } \\ = \sqrt{ {8}^{2} + {5}^{2} } \\ = \sqrt{64 + 25} \\ = \sqrt{89} \: \: \: \: \: \: \: \: \: \:$

We have the final answer as

$\sqrt{89} \: \: \: \: units \\$
