Find the value of x that makes the quadrilateral a parallelogram
What is x?​

Answers

To make it a parallelogram, the diagonals have to bisect each other (6x=3x+2)

Calculate and you will get x = 2/3

The value of x that makes the quadrilateral a parallelogram is 2/3.

What is a parallelogram?

A special form of quadrilateral called a parallelogram has both pairs of its opposite sides parallel and equal.

We have a quadrilateral.

To show that the quadrilateral is a parallelogram:

If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram.

That means,

6x = 3x + 2

3x = 2

x = 2/3

Therefore, the value of x is 2/3.

What is an equation of the line that passes through the point (-6,-2)(−6,−2) and is parallel to the line 3x-2y=23x−2y=2

Answers

Answer:

y = 3/2x + 7

Step-by-step explanation:

If two lines are parallel to each other, they have the same slope.

The first line is 3x - 2y = 2. First, let's put this into standard form.

3x - 2y = 2

Add 2y to both sides to make y positive.

3x = 2y + 2

Subtract 2 from both sides to isolate y.

3x - 2 = 2y

Isolate y further by dividing both sides by 2.

3/2x - 1 = y or y = 3/2x - 1

This is now your first line. Its slope is 3/2. A line parallel to this one will also have a slope of 3/2.

Plug this value (3/2) into your standard point-slope equation of y = mx + b.

y = 3/2x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (-6, -2). Plug in the x and y values into the x and y of the standard equation.

-2 = 3/2(-6) + b

To find b, multiply the slope and the input of x (-6)

-2 = -9 + b

Now, add 9 to both sides to isolate b.

7 = b

Plug this into your standard equation.

y = 3/2x + 7

This equation is parallel to your given equation (y = 3/2x - 1) and contains point (-6, -2)

Hope this helps!

Stuff mart sells ice cream toppings in two different packages. Package one has eight blueberry toppings for $22. Package two has four blueberry and seven strawberry toppings for $22. Find the cost of each topping

Answers

Answer:

the cost of the blueberry packing be $2.75 and the cost of the strawberry topping be $1.57

Step-by-step explanation:

The computation is shown below:

Let us assume the blueberry topping be x

And, the strawberry topping be y

Now as per the question

8x = $22

Divide by 2 to the both sides

4x = $11

x = $11 ÷ 4

= $2.75

And,

4x + 7y = $22

Now put the x value in the above equation

4 × (11 ÷ 4) + 7y = $22

11 + 7y = $22

7y = $22 - $11

7y = $11

y = $11 ÷ 7

= $1.57

Hence, the cost of the blueberry packing be $2.75 and the cost of the strawberry topping be $1.57

sin(30)° = [tex]\frac{10}{x}[/tex]

[tex]\frac{1}{2}= \frac{10}{x}[/tex]

What is the result when we simplify the expression ( 1 + 1 /x ) ( 1 − 2/x + 1 ) ( 1 + 2/ x − 1 ) ?

Answers

Step-by-step explanation:

Let y be 1/x. Then 2y = 2/x.

We wish to simplify (1 + y)(2 - 2y)(2y).

(1 + y)(2 - 2y)(2y)

= 4y(1 + y)(1 - y)

= 4y(1 - y²)

= 4y - y³

= 4/x - 1/x³.

P.S. Writing it as (4x² - 1)/x³ is fine.

All our arts and occupations lie wholly on the surface; it is on the surface that we perceive their beauty, fitness, and significance; and to pry below is to be appalled by their emptiness and shocked by the coarseness of the strings and pulleys. In a similar way, psychology itself, when pushed to any nicety, discovers an ABHORRENT baldness, but rather from the fault of our analysis than from any poverty native to the mind. And perhaps in aesthetics the reason is the same: those disclosures which seem fatal to the dignity of art seem so perhaps only in the proportion of our ignorance; and those conscious and unconscious artifices which it seems unworthy of the serious artist to employ were yet, if we had the power to trace them to their springs, indications of a delicacy of the sense finer than we conceive, and hints of ancient harmonies in nature.
