Notice that all eight of the angles in the center of the pattern meet to form a circle. Let a° represent the measure of each pin

k central angle and b° represent the measure of each green central angle.
Which of the following equations are true? Select all that apply.
(1) 4a° = 180°
(2) 2b° = 90°
(3) 4a° + 4b° = 360°
(4) a° = 90° - b°
(5) 2(a° + b°) = 180°

For each of the figures, write an absolute value equation to satisfy the given solution set.
Valentin [98]

Answer:

|x-1|=5

Step-by-step explanation:

From the diagram you can see that the solutions of the equation are x_1=-4 and x_2=6

1. Find the midpoint between -4 and 6:

1/2(-4+6)=1

2. Find the distance between points x=1 and x=6 (or between x=1 and x=-4):

d=6-1=5

3. Writhe an absolute value equation (the distanse from endpoints x_1=-4 and x_2=6 to the midpoint x=1 is equal 5):

|x-1|=5

What is the value of x? 6(-3-x)-2x=14
Lera25 [3.4K]
The equation given in the question has one unknown variable in the form of "x" and only one equation is required to find the value of the unknown variable. So it is absolutely possible to find the exact value of "x".
6(-3 - x) - 2x = 14
-18 - 6x - 2x = 14
-18 - 8x = 14
Multiplying both sides of the equation by -1 we get
8x + 18 = - 14
Dividing both sides by 2 we get
4x + 9 = - 7
4x = - 7 - 9
4x = - 16
x = - 16/4
  = - 4
So the value of "x" comes out to be equal to - 4. I hope the procedure is clear enough for you to understand.

Answer: D) w = 9 feet

Work Shown:

L = \sqrt{w^2+h^2}\\\\L^2 = w^2+h^2\\\\L^2-h^2 = w^2\\\\w^2 = L^2-h^2\\\\w = \sqrt{L^2-h^2}\\\\w = \sqrt{15^2-12^2}\\\\w = \sqrt{225-144}\\\\w = \sqrt{81}\\\\w = 9\\\\

That points us to the final answer choice D.
