Which of the following statements is true about the graph and the shading of the inequality
andreyandreev [35.5K]

Answer:

The graph is a solid line, and the shading is above the line.

Step-by-step explanation:

Given

x + y \ge 1

Required

Describe the graph of the inequality

We have:

x + y \ge 1

Subtract x from both sides

y \ge 1-x

The sign \ge implies that the graph has a solid line

The sign \ge which means greater than or greater also implies that the upper region is shaded

Ryan is putting a clothesline in his rectangular backyard. He wants to put it between two trees on the edge of his property. He
Rama09 [41]

Answer:  

  • 25m  

Explanation:  

The first figure attached is the sketch of the property mentioned on the question, where all the lengths listed are in meters.

The second figure attached identifies a right triangle whose hypotenuse, c, is the smallest length that the clothesline can measure; and the legs measure 20m, and 20m - 10m = 15m.  

Now, you can use the Pythagorean theorem to find the smallest length of the clothesline:  

      c^2=(20m)^2+(15m)^2\\\\c^2=625m^2\\\\c=\sqrt{625m^2} \\\\c=25m\longleftarrow answer

Whats 3y+53=7y-55 whats the answer ? *Will be marked brainly king*
vova2212 [387]
<span>3y + 53 = 7y - 55 is a three step equation. Our goal is to get 'y' by itself.

First we subtract 3y on both sides of the equation.

</span>3y + 53 = 7y - 55
-3y          -3y

53 = 4y - 55

Then we add 55 on both sides of the equation.

53 = 4y - 55
+55       +55

108 = 4y

Finally we divide 4 on both sides.

108 = 4y
-----   -----
  4       4

27 = y is the answer
