Greetings.
The answer is x = -2.
Explanation:
By solving the Absolute-Value Equation. We give them 2 conditions.
<em>When x ≥ 0 and When x < 0</em>
<em>The different is that When x ≥ 0, |x-a| = x-a as defined.</em>
<em>And when x < 0. |x-a| = -x+a as defined.</em>
( 1 ) - When x ≥ 0 for |x-1| and |x+5|
When x ≥ 0, |x-1| = x-1 and |x+5| = x+5
Therefore, x-1 = x+5
Because the equation is false. Therefore, The condition (1) doesn't apply.
( 2 ) - When x ≥ 0 for |x-1| and x < 0 for |x+5|
This time, we try another condition.
When x ≥ 0, |x-1| = x-1 and When x < 0, |x+5| = -x-5.
And we get the answer, |x-1| = |x+5| when x = -2.
But we haven't tried the last condition.
( 3 ) And that is when x < 0 for both terms.
|x-1| = -x+1 (x < 0)
|x+5| = -x-5 (x < 0)
The equation is not true. Therefore, the answer is x = -2.
I can’t help and also it would be too late so sorry also I’m doing this to ask a question sorry again
Simplify 2/3 - 1/7 to 11/21
10/21 + 11/21
Simplify
The answer is 1.
Answer:
4.8 smaller pieces
Step-by-step explanation:
Total length of wood = 3.6 feet
Length of each piece = 0.75 feet
How many smaller pieces will they be able to make?
Number of smaller pieces of wood = Total length of wood / Length of each piece
= 3.6 feet / 0.75 feet
= 4.8 smaller pieces
Number of smaller pieces of wood = 4.8
Current density of solution a/m2 is given below
Step-by-step explanation:
Current density is the measure of current generated per unit surface area of electrode.
Eg: In microbial fuel cell/fuel cells, if you are using electrode with size of 5cm x 2cm and current produced is 200mA, then current density will be,
CD= Current/(projected area of electrode)
area of rectangle= LxB= 5cm x 2cm =10cm2
CD= 200mA/10cm2
CD= 20mA/cm2
Your Current will be 200mA.
Current density will be 20mA/cm2.
