Darina [25.2K]2 years ago
3 0

Answer:

x = 3

Step-by-step explanation:

A parallelogram must have two pairs of parallel sides.

For this to be true, the alternate exterior angles of the diagonal must be congruent.

Hence the equation,

<u>10x + 4 = 13x - 5</u>

Simplify.

<u>9 = 3x</u>

<u>x = 3</u>

Which graph shows the solution of the inequality −|x − 2| + 9 &gt; 6?
mariarad [96]

answer is -1 < x < 5

-|x - 2|+ 9 > 6

Rearrange the terms

-|x - 2| > 6 - 9

-|x - 2| > - 3

then divide both sides of the inequality by the co- efficient of variable

|x - 2| < 3

convert the absolute inequality to standard inequality

-3 <x - 2 < 3

separate compound inequalities into system of inequality

{x - 2}> -3

{x - 2 < 3}

Rearrange variable to the left side of the equation

x > -3 + 2                    

calculate the sum or difference

x > -1

x -2 < 3

Rearrange variable to the left side of the equation

x < 3 + 2

calculate the sum or difference

x < 5

x > -1 and x < 5

Find intersection

-1 < x < 5

Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are deemed equal which is shown by the symbol =. Where as in an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
