Solve x in 2|x+ 6| + 9 = 19

Mathematics

Nata [24]2 years ago

Answer has two solutions: x = -11, x= -1

2|x+6| + 9 = 19
2|x+6| = 10
(Divide 2 on both sides to get rid of multiplication)
|x+6| = 5

|x+6| = 5
|x+6| = -5

Solving positive one first:

|x+6| = 5
x+6 = 5
x = -1

|x+6| = -5
x+6 = -5
x = -11

Answer has two solutions: x = -11, x = -1

Answer: x=-1

Step by step:

2|x+6|+9=19

Subtract 9 from both sides.

2|x+6|=10

Divide both sides by 2

|x+6|=5

Use the definition of absolute value.

x+6=5

Subtract 6 on both sides

x=-1

Hope this helped! :)

What is the slope of a line perpendicular to 3x- 2y= 6
Tema [17]

Answer:

y = (-2/3)x + 5

2y=3x-6 Then divide by 2. y=3/2x-6 Now it is in slope-intercept form. The slope for this particular equation is 3/2 (m). The slope of a line that is perpendicular to this would be -2/3, the negative reciprocal of 3/2.

How does the area of the polygons compare to π? ( π is 3.14)
soldi70 [24.7K]

The area of the polygons compare to π in the way that as more angles and sides are added to a polygon the polygon becomes closer to a circle; the perimeter slowly changes to circumference. Π is used to find the area and circumference of a circle, so as polygons come closer to becoming circles π becomes more strongly associated to the polygon. You can even use π to find the approximate area of a circle if you use the same formula (as you would to find the area of a circle) on a polygon. Another way to go about it is like this…

You can find the area of a circle if you know the circle’s circumference by using these steps:

<span>1.         Divide the circumference by π to find the diameter of the circle.</span>

<span>2.         Divide the diameter by 2 to find the radius of the circle.</span>

<span>3.         Now that you have the radius you can use the formula Area= πr2 to find the area of the circle.</span>
