Can you describe it more? What is the wooden part or concrete part? Add a picture?
|-x + 2| = 12
|-x + 2| = 12 or |-x + 2| = -12
-x + 2 = 12 or -x + 2 = -12
- 2 - 2 - 2 -2
-x = 10 or -x = -14
-1 -1 -1 -1
x = -10 or x = 14
Solution Set: {-10, 14}
First, find the GCF. For these two numbers, it is 36. (Because 36 times 1 is 36 and 36 times 2 is 72)
Divide both sides by this, which gives you a
2:1 ratio
Answer:
b) The distance between −12 and −1 is ∣∣−12−(−1)∣∣
Step-by-step explanation:
The point A = -1
The point B = -12
To find The distance from A to B on the number line.
Now, distance of a point B from the point A is given as I B - A I
Definition of Modulus Function
I x I = x, if x > 0
= -x if x< 0
Similarly, here the distance is given as
I B - AI = I (-12) - (-1) I = I -12 + 1 I
= I -11 I = -(-11) = 11 ( as x < 0)
or the distance of point B from point A = + 11 units.
Hence, I B - AI = ∣∣−12−(−1)∣∣
The strategy to graph a line actually doesn't depend on the form the equation is presented: it can be the standard form, the slope intercept form, or any other way to write it.
The key point is that you can draw a line if you know two of its points. In fact, all you have to do is draw and connect them.
To sample two points from the equation, just pick any two values for x, and compute the correspondent value for y.
For example, given the line y=3x-7, we can sample x=0 and x=1 (again, this is a totally arbitrary choice), and compute
So, the line passes through the points (0,-7) and (1,-4). Draw these two points and connect them, and you'll have the line.
