Five times the difference of twice a number and eleven is negative twenty-five. Find the number.

1 answer:

4 0

Let x be the number.
The equation would be: 5 (2x - 11) = -25
Multiply 2x - 11 by 5 so that it is 10x - 55
Now, move the -55 to the other side of the equation so 10x = -25 + 55
Subtract so 10x = 30
Now divide 30 by 10 to find x.
x = 3

Find the distance between A(1, -1) and B(4, 3).

Greeley [361]

Answer:

<h2>The answer is 5 units</h2>

Step-by-step explanation:

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

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

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

From the question the points are

A(1, -1) and B(4, 3)

The distance between them is

$|AB| = \sqrt{ ({1 - 4})^{2} + ({ - 1 - 3})^{2} } \\ = \sqrt{( { - 3})^{2} + ({ - 4})^{2} } \\ = \sqrt{9 + 16} \\ = \sqrt{25} \: \: \: \: \: \: \: \: \\ = 5 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\$
