Which conjunction or disjunction is equivalent to the given absolute value inequality?

A quilt is designed using a square pattern. Each square contains two rectangles. Each rectangle contains a shaded rhombus.

leva [86]

The sum of angles in any Rhombus is 360 degrees.Opposite angles of a rhombus are congruent.

Two of the adjacent angles are 2x+20 and 50 degrees.

The opposite angles measure 2x+20 and 50 degrees.

Sum of angles in any Rectangle is 360

2x+20+50+2x+20+50=360

Adding line terms,

4x+140=360

Subtracting 140 both sides:

4x=220

Dividing both sides by 4

x=55

Option B. 55 is the right answer.

This is an interesting problem.

But first, let us define what are the three possible cases :

A system of linear equations : a system of equation is when you have two equations with the same unknown variables, that you need to solve both together. Example : "x+y = - 7 AND x + y = - 4" are two equations that form a system of equation.

Plus they are linear, a linear equation is simply an equation of the form : y = ax + b where a and b are real numbers.

Here for example x + y = - 7 is a linear equation. Because y = 1 × x - 7

where a = 1 and b = - 7.

Consistent Dependent : A system of equation is consistent Dependant when it has an infinite number of solutions.

<h2><u><em>When this is the case, the graphs of the lines in the system are the same, meaning the equations in the system represent the same line. </em></u></h2><h2 />

Consistent Independent : A system of equation is consistent Dependant when it has exactly one solution.

<h2><em><u>When this is the case, the graphs of the lines in the system cross at exactly one point. </u></em></h2><h2 />

Inconsistent : A system of equation is Inconsistent if it haas no solutions.

<h2><em><u>When this is the case, the graphs of the lines in the system do not intersect, meaning they are parallel. </u></em></h2><h2 />

Now, with those definitions above, we can work on our problem :

1. x + y = - 7 and x + y = - 4

Look at the picture attached the lines are parallel to each other so here the answer is Inconsistent

2. Same line : consistent dependent

3. Parallel Lines : Inconsistent

4. Lines cross at exactly one point :Consistent Independent

5. Lines cross at exactly one point : Consistent Independent.

You can see the graph of each systems in the pictures attached below.
