Answer:
MN = 130
Step-by-step explanation:
since M is at the midpoint of LN , then
LM = MN
7x - 24 = 6x - 2 ( subtract 6x from both sides )
x - 24 = - 2 ( add 24 to both sides )
x = 22
Then
MN = 6x - 2 = 6(22) - 2 = 132 - 2 = 130

14. Write an equation of a line that is parallel to the line 2x – 3y = 6. Explain how you know that the graph of
your equation is parallel to 2x – 3y = 6.
15. A student drew the line y = 2x + 3
a. Write equations for two lines that are perpendicular to this line. Justify your answer.
b. What do you notice about the slopes of these two lines? What generalization can you make about two lines
that are both perpendicular to the same line?
Answer:
Step-by-step explanation:
14. y = -2/3x + 10. This is parallel to 2x -3y because they have the same slope.
15. y = -1/2x and y = -1/2x + 2. These are perpendicular because the slope is the opposite reciprocal to the slope of y = 2x + 3, which is 2.
The slopes of the lines of the 2 equations are the same. Because of that, we can state that 2 lines that are perpendicular to the same line are parallel. This can be further supported by the Perpendicular Transversal Theorem, which says the same thing.

From the graph:
slope:
Slope is the steepness of a line as it moves from LEFT to RIGHT. Slope is the ratio of the rise, the vertical change, to the run, the horizontal change of a line. The slope of a line is always constant (it never changes) no matter what 2 points on the line you choose.
Take any points:
(0,0) and (5,1)
slope m = y2 - y1 / x2 -x1
= 1 - 0 / 5 - 0

What is greater than symbol refer?
In mathematics, the larger than sign is used between two numbers to indicate that the first number is greater than the second. For instance, 10 > 5. 10 is more than 5 in this case.The greater than symbol, which consists of two strokes of equal length joined at an acute angle at the right, is always pointed toward the greater value in inequality. ( >).What is lesser than symbol refer?
In a situation when one number is less than another, a less than symbol is positioned between the two numbersWhen referring to an inequality, the less than symbol () represents the smaller value where two strokes of equal length meet at a sharp angle on the left.The reader may easily understand the message thanks to the larger than less than sign, which also decreases the time complexity.What is equal to symbol refer?
The "equal to" symbol is used to indicate that two numbers or values are equal. The greater than and less than signs are in conflict with this one. We employ the equal to symbol even while writing equations. '=' is used to indicate it.Hence, 0.123 < 2 > 0.1002, is the true statement after inserting symbols.

The length of the missing side is 39 units
What is parallelogram:The parallelogram is a simple 2D-shaped quadrilateral with two pairs of parallel sides. In a parallelogram, the opposite sides and opposite angles are equal.
Here we have,
The length of the sides of a parallelogram is 2x+10, 5x- 20 and 4x-1
As we know parallel lines of a Parallelogram are equal
Take any two sides as equal and find the missing side
Let the sides with lengths be equal 2x+10, 5x- 20
=> 2x+10 = 5x- 20
=> 5x - 2x = 20+ 10
=> 3x = 30
=> x = 10
Therefore, the lengths of the 3 sides are
2x+10 = 2(10) + 10 = 30
5x- 20 = 5(10) - 20 = 30
4x-1 = 4(10) - 1 = 40 - 1 = 39
The length of the missing side is 39 units

a painter leans a ladder against a vertical wall. the top of the ladder is 15 meters above the ground. when the bottom of the ladder is moved 3 meters farther away from the wall, the top of the ladder is 11 meters above the ground. what is the length of the ladder? round to the nearest hundredth of a meter.
From the ground the length of the ladder is 15 feet.
Step-by-step explanation:
From the Pythagorean Theorem, the situation described can be expressed mathematically as:
x² +9² = (x+3)²
or,
x² + 81 = x² + 6x + 9
Now, cancelling equal terms on either side of the equation and reducing gives:
x = 12
Since the ladder is defined to be 3 feet longer than the distance of its foot to the wall the ladder’s length must be:
12 feet + 3 feet

A linear equation in two variable can be written in general form as y = mx + c. The slope and y-intercept are 1 / 2 and 30 respectively.
What is a Linear equation ?A linear equation is an equation having only one variable.
Its degree is one and it can be used to find the value of only one unknown quantity.
Suppose, the cost be y and the number of minutes be x.
Then, the slope from the given table can be found by by taking the ratio of the difference of cost and minutes from any two rows of the table as given below,
Slope = (50-40)/(40-20)
=> slope = 1/2
Now, the equation for the line representing the given table can be given as,
(y-40)/(x-20) = 1 / 2
=> y - 40 = 1 / 2 (x - 20)
=> y = x / 2 - 10 + 40
=> y = x / 2 + 30
The y-intercept is given at x = 0.
therefore y-intercept is given as,
y = 0 / 2 + 30
y = 30.
Hence, the slope is given as 1 / 2 and the y-intercept is 30.

A rectangle is inscribed with its base on the x-axis and its upper corners on the parabola. What are the dimensions of such a rectangle with the greatest possible area?.
The dimensions of the rectangle such that the rectangle have the greatest area is length = 8 and width = 4 .
In the question ,
it is given that ,
a rectangle is inscribed with its base on the x axis , and its upper corner on the parabola y = 12 − x² ,
let the coordinate of the upper right corner be P(x,y) ,
and A be the area of the rectangle .
the point P lies on the parabola , given y = 12 − x² ,
So, P = P(x,12−x²)
Due to symmetry of the rectangle, the width of rectangle is half the distance between P and the y axis ,
that means width = 2x and length = y .
Area of the rectangle = width × Length
= 2x * y
= 2x (12 − x²)
= 24x - 2x³
To maximize the area we differentiate Area with respect to x ,
we get ,
dA/dx = 24 - 6x²
for critical point dA/dx = 0 ,
24 - 6x² = 0
6x² = 24
x² = 4
x = ±2 ,
since length cannot be negative ,
So , x = 2 .
to check for maximum and minimum ,we differentiate Area with respect to x,
we get
d²A/dx² = -12x
substituting , x = 2 ,
we get -12 < 0, So , the area is maximum .
hence the width = 2*2 = 4
and length = 12 - 4 = 8
and the maximum area is 32 .
Therefore , The dimensions of the rectangle such that the rectangle have the greatest area is length = 8 and width = 4 .

Emma and Evie are saving for a new car. Emma has $2000 and she plans to save an additional $50 per month. Evie has $1600 and she plans to save an additional $100 per month. In how many months will Emma
and Evie have the same amount of money saved?
After 12 months for Emma and 10 months for Evie they will have the same amount of money that is $ 2,600
Given:
Case 1 : Amount of money Emma already has = $ 2000
Amount she plans to save per month = $ 50
Thus according to the above data after 12 months Emma would have
12 × 50 = 600 + 2000
this is equal to $ 2600
Case 2 : Amount of money Evie has = $ 1,600
Amount of money she plans to save every month = $ 100
Thus after 10 months she will have 10 multiplied by 100 which is $ 1000
Thus the total amount she will have = 1000 + 1600
which is equal to $ 2,600
Thus after 12 months for Emma and 10 months for Evie they will have the same amount of money that is $ 2,600

express the interval shown on the number line in inequality notation.
The given interval shown on the number line in inequality notation as (3, 6).
What are inequalities on a number line?
Inequalities on a number line allow us to visualise the values that are represented by an inequality.
To represent inequalities on a number line we show the range of numbers by drawing a straight line and indicating the end points with either an open circle or a closed circle.
An open circle shows it does not include the value.
A closed circle shows it does include the value.
The left endpoint is 3. The right endpoint is 6. Both endpoints are open holes, meaning we do not include them as part of the green shaded solution region. If x is a solution, then the solution can be described as
3 < X < 6 which converts to the interval notation (3, 6) . The curved parenthesis says "do not include the endpoint".
Note: this is not ordered pair notation (x,y).
