Answer:

The answer to your question is below

Step-by-step explanation:

Process

1.- Get two points of each line to find the equation of each line

   Continuous line    A (-10, 0)  B (0, 9)

   Dotted line            C (-2, -3)   D (0, -10)

 Slope continuous line    m = \frac{9 - 0}{0 + 10} = = \frac{9}{10}

 Slope dotted line     m = \frac{-10 + 3}{0 + 2} = \frac{-7}{2}

2.- Get the equation of each line

     Continuous line    y + 0 = 9/10 (x + 10)

                                   y = 9/10x + 9

      Dotted line          y + 3 = -7/2(x + 2)

                                    y + 3 = -7/2x - 7

                                    y = -7/2x -7 - 3

                                    y = -7/2x - 10

3.- Find the inequalities

   <u> Continuous line</u> (we need the upper area of the line, we use ≥)

                               y ≥ 9/10x + 9

   The <u>Dotted line</u> (we also need the upper area, we use >)

                              y > -7/2x - 10

The area of the square rug is 121 square feet. what is the length of the side of the rug
hram777 [196]

Answer:

11 feet

Step-by-step explanation:

Squares have the same length and width. So you just take the square root of teh area to find both.

√121 = 11

Answer:

Step 2

Step-by-step explanation:

Because when you see number (70)

it's a pos+ so take it to another side to be neg- .

Then : 40-70=-30

5 p. m.                  {}                          74°F

6 p. m.                 {}                           74°F

7 p. m.                       {}                     71°F

8 p. m.                      {}                      68°F

9 p. m.                          {}                  65°F

10 p. m.                  {}                         62°F

11 p. m.                        {}                    61.5°F

12 a. m.                        {}                    61°F

With the above table as the data points, the graph can be drawn

From Excel, The Mean temperature is approximately 68.1°F

The standard deviation is 6.079 °F
