Opposite sides JK and ML are equal and parallel (with slopes of -1/5 and 1/5, respectively), and opposite sides KL and MJ are equal and parallel (with slopes of 7/3 or 7). /3) We can conclude that JKLM is a parallelogram. 

To determine if JKLM is a parallelogram, we need to check if its opposite sides are parallel and equal in length.

First, we can find the lengths of the sides using the distance formula:

JK = [tex]\sqrt{(1 - (-4))^2 + (3 - 2)^2} = \sqrt{25} = 5[/tex]

KL = [tex]\sqrt{(-4 - (-1))^2 + (2 - (-5))^2} = \sqrt{58}[/tex]

LM = [tex]\sqrt{(-1 - 4)^2 + (-5 - (-4))^2} = \sqrt{26}[/tex]

MJ = [tex]\sqrt{(4 - 1)^2 + (-4 - 3)^2} = \sqrt{50}[/tex]

Next, we can find the slopes of the sides using the slope formula:

Slope of JK = (2 - 3)/(-4 - 1) = -1/5

Slope of KL = (-5 - 2)/(-1 - (-4)) = 7/3

Slope of LM = (-4 - (-5))/(4 - (-1)) = 1/5

Slope of MJ = (3 - (-4))/(1 - 4) = 7/3

Since opposite sides, JK and ML have the same length and are parallel (they have slopes of -1/5 and 1/5, respectively), and opposite sides KL and MJ have the same length and are parallel (they have slopes of 7/3 and 7/3, respectively), we can conclude that JKLM is a parallelogram.

Answer:8

Step-by-step explanation:

Because Angle GJH is 90 degrees, Angle HJZ is also 90 degrees. (Because all right angles are 90 degrees)

Now, find Angle WJZ

90 - 18 = 72 degrees

By the Vertical Angles Theorem, Angle GJL is congruent to Angle ZJW

Now solve for x

72 = 9x

x = 8

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Solving a Single Variable Equation:

3.1 Solve : -3x2+5 = 0

Subtract 5 from both sides of the equation :

-3x2 = -5

Multiply both sides of the equation by (-1) : 3x2 = 5

Divide both sides of the equation by 3:

x2 = 5/3 = 1.667

When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:

x = ± √ 5/3

The equation has two real solutions

These solutions are x = ±√ 1.667 = ± 1.29099

Two solutions were found :

To fill a 6-inch thick layer of topsoil for a new 28 feet by 17 feet garden, you will need 79.33 cubic yards.

The volume is the product of the multiplication of the thickness, length, and width.

12 Inches = 1 Feet

6 inches = 0.5 Feet (6/12)

The length of the garden = 28 feet

The width of the garden = 17 feet

The thickness of the soil = 0.5 feet

Volume of the topsoil = 28 x 17 x 0.5

The solution of the inequality is -4≤x<7. Therefore, option D is the correct answer.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

The given inequality is -12≤2x-4<10.

Here, -12≤2x-4

Add 4 on both the sides of an inequality, we get

-8≤2x

Divide 2 on both the sides of an inequality, we get

-4≤x

Now, 2x-4<10

Add 4 on both the sides of an inequality, we get

The inequality is |x-9| ≥ 4, and its solution set is (5,13).

An Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

The inequality of the form |x-a| ≥ k means that the distance between x and a is greater than or equal to a certain value, k.

If the solution set is (5,13), it means that x is a number between 5 and 13, but not including 5 or 13. In other words, 5 < x < 13.

To find the value of a and k, we need to look for the midpoint of the solution set, which is (5+13)/2 = 9.

The distance between 9 and either endpoint (5 or 13) is 4, which is the value of k.
