Answer:

13x+9=30

13x=30+9

13x=39

divide both sides by 13

x=3

12x+1=-13

12x=-13-1

12x=-14

divide both sides by 12

x=7/6

x+2+4=11

x+6=11

x=11_6

x=5

If the points (-8, 7) and T (6,-3) are on a line segment, find the length of ST.​
larisa86 [58]

Answer:

The answer is

<h2>2√74 or 17.20 units</h2>

Step-by-step explanation:

The length of w line segment 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

S(-8, 7) and T (6,-3)

The length of ST is

|ST|  =  \sqrt{ ({ - 8 - 6})^{2} +  ({7 + 3})^{2}  }  \\  =  \sqrt{ ({ - 14})^{2} +  {10}^{2}  }  \\  =  \sqrt{196 + 10}  \\  =  \sqrt{296}  \\  = 2 \sqrt{74}  \\  = 17.2046505...

We have the final answer as

<h3>2√74 or 17.20 units</h3>

Hope this helps you

Which sentence best describes the independent and dependent variables in the following problem? The parking garage charges $3 fo
alexandr402 [8]
Ok so the dependent variable would be $1.45 for each addition hour. The cost depends on every hour so u can't really calculate it unless u have the hours.
$3 is independent since it's only charged on the first hour. It doesn't rely on any other information.
