In English: calculate the value of x (if it exists) satisfies the equation the absolute value here if there is no value of x satisfies.give your reasons: 2[3x-8] = 10
Talking about absolute value, that is about the module. Apparently the sign "[]" module mark "| |". Let's remember what is a module: |X|=X if X>0 or X=0and |X|=-X if X<0.The module requires two solutions.
2|3x-8| = 10 divide the equation by 2.|3x-8| =5
get the two systems
1.1) 3x-8>0 or 3x-8=01.2) 3x-8=5
2.1) 3x-8<0 2.2) -3x+8=5
Solved:1.1) 3x-8>0 or 3x-8=0X>2 and 2/3 or X=2 and 2/3 ------ the first condition
1.2) 3x=13x=4 and 1/3 -------- the second condition
Solution 1: x=4 and 1/3
2.1) 3x-8<0 2.2) -3x+8=5
2.1) 3x-8<0 X<2 and 2/3 ------ the first condition
2.2) -3x=-3x=1 -------- the second condition
Solution 2: x=1.
Obyedinenie decisions system 1 and system 2.
General answer: x1=4 1/3 ; x2=1
Answer:
where is the graph
Step-by-step explanation:
??????
Workers pay an average of 6.2 percent which is 127,000 a year. But <span>employers pay a matching amount for a combined contribution of 12.4 percent of earnings.
Meaning you are either getting 6.2 percent for being a WORKER.
or getting 12.4 percent for being a EMPLOYER.
In this question you are looking for employer so the answer is 12.4

Answer:
F the point is 3.16
Explantion:
the point is 3.16, which is close to 3.2
It is given that area( Δ ab c) =6 square units.
Also ab║d e
⇒b d =4 b c
I have depicted picture below.
Consider Δ cde in which points a and b are in the interior such that ab║de.
So, as you know that if in a triangle line joining two points is parallel to third side then the two sides are proportional.i.e
⇒ca/ae =cb / bd
Also, ∠ c is common.
∴Δcab is similar to Δ cde.
As we know if ratio of areas of two similar triangles is square of their corresponding sides.
=
⇒6/Δcde =1/4
⇒Ar (Δ cde)=6×4
Ar (Δ cde) =24 square centimeter
