Crazy boy [7]3 years ago

4 0

Answer:

A -6 < x ≤ -3

Step-by-step explanation:

21 ≤ - 3(x - 4) < 30

Divide all parts by -3. Remember that flips the inequalities

21/-3 ≥ - 3/-3 (x - 4) > 30/-3

-7 ≥ (x - 4) > -10

Add 4 to all sides

-7+4 ≥ x - 4+4 > -10+4

-3 ≥ x > -6

Rearranging the order

-6 < x ≤ -3

Using the distance formula, find the distance between these two points. Round to the nearest tenth. (8,9) and (3,2)

Masja [62]

Answer:

The answer is

<h2>8.6 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

(8,9) and (3,2)

The distance between them is

$d = \sqrt{( {8 - 3})^{2} + ( {9 - 2})^{2} } \\ = \sqrt{ {5}^{2} + {7}^{2} } \\ = \sqrt{25 + 49} \\ = \sqrt{74} \: \: \: \: \: \: \: \: \: \: \\ = 8.60232...$

We have the final answer as

<h3>8.6 units to the nearest tenth</h3>
