When two parallel lines have a transversal cutting those parallel lines, the alternate angle theorem holds true. According to the alternate angle theorem, all alternate angles are equal.

We have a similar circumstance here, where we are employing the alternate angle theorem approach to design and build two parallel lines. To prove that the two alternate angles are equal and the lines are parallel, we must first identify the two alternate angles.

The two alternate angles are:

∠ MLN and ∠ MJK

The equation of the line in slope-intercept form is: y = -4/5x - 8/5.

Using two points on the line, say, (-2, 0) and (3, -4), follow the steps below to find the equation of the line:

Step 1: Find the slope of the line

Slope (m) = (-4 - 0)/(3 -(-2))

Slope (m) = -4/5

Step 2: Find the y-intercept (b)

Substitute m = -4/5 and (x, y) = (-2, 0) into y = mx + b

0 = -4/5(-2) + b

0 = 8/5 + b

0 - 8/5 = b

b = -8/5

Step 3: Substitute m = -4/5 and b = -8/5 into y = m + b

y = -4/5x - 8/5

Thus, the equation of the line in slope-intercept form is: y = -4/5x - 8/5.

Given function is the logarithmic function f(x) = ln(x).

Now, f(x) has a domain(D) of all real numbers greater than zero and a range(R) of all real numbers.

i.e., f : D → R defined by f(x) = ln(x)

So if an inverse exist for f(x), then, [tex]f^{-1}(x)[/tex] will have R as its domain and D as its range.

i.e.,  [tex]f^{-1}[/tex] : R → D defined by [tex]f^{-1}(x) = e^x[/tex].

Because f( [tex]f^{-1}(x)[/tex] ) = ln([tex]e^x[/tex]) = x, that is the identity function.

So [tex]e^x[/tex] is the inverse of ln(x).

The equation of point slope form of (4,6) and (10,30) is -4x + y + 10 = 0.

A straight line is represented using its slope and a point on the line using point slope form. In other words, the point slope form is used to determine the equation of a line whose slope is "m" and passes through the point (x1, y1).

given that

the coordinates points are (4, 6) and (10, 30)

(x1,y1) = (4,6)

(x2, y2) = (10,30)

The formula of point-slope is

(y - y1) = m(x - x1)

Here,

x1 = 4 and y1 = 6 but we don't know the value of

m.

now,find the value of m using the following formula

[tex] m = \frac{(y2 - y1)}{(x2 - x1)}[/tex]

now, substitute the values, we get

[tex]m = \frac{(30 - 6)}{(10 - 4)}[/tex]

[tex]m = \frac{24}{6}[/tex]

m = 4

so, the value of m is 4.

substitute these values into the point-slope formula

(y - 6) = 4(x - 4)

y-6 = 4x - 16

y = 4x -16 + 6

y = 4x - 10

-4x + y + 10 =0

Hence, the equation of point slope form of (4,6) and (10,30) is -4x + y + 10 = 0.

So, according to the question

From figure we can say that there is present five rectangle of same size.

So far finding the area of this irregular figure we have to find the area of this single rectangle and multiply it by 5 so from that process we can calculate the area of this irregular figure.

Now first we have to learn about the area,

The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a shape or planar lamina.

So, we know

The area of one rectangle = l x w

Now, putting the values = 3 x 2 = 6

So,

The area of this irregular figure = 5 ( The area of one rectangle )

                                                   = 5 x 6

The dimensions of the sticker are 6 centimeters and 9 centimeters, respectively.

According to the statement, we find a rectangular sticker whose perimeter and area are known. By the perimeter and area formulas of the rectangle we have the following system of equations:

x · y = 54                      (1)

2 · (x + y) = 30              (2)

By (2):

2 · x + 2 · y = 30

2 · x = 30 - 2 · y

x = 15 - y

(2) in (1):

(15 - y) · y = 54

15 · y - y² = 54

y² - 15 · y + 54 = 0

(y - 9) · (y - 6) = 0

The solutions are y₁ = 9 and y₂ = 6, respectively.

By (2):

x₁ = 15 - y₁

x₁ = 15 - 9

x₁ = 6

x₂ = 15 - y₂

x₂ = 15 - 6

To find the number of candy pieces collected:

x - 7 - 10% × x = 63

x - 7 - 0.1x = 63

x - 0.1x = 63 + 7

Luis and Baca would be the same weight after 60 weeks of weightlifting.

A linear equation is one in which the highest power of the variable is consistently 1. A one-degree equation is another name for it. A linear equation with one variable has the formula Ax + B = 0, which is its standard form. x is a variable, A is a coefficient, and B is constant in this situation.

To create an equation that Luis and Baca can use to determine how long it will take for them to be the same weight:

Let the time taken by Luis and Baca to be of the same weight be x weeks,

Given:

Initial weight of Luis = 194 pounds

Initial weight of Baca = 218 pounds

Then,

Weight gained by Luis in x weeks = 0.6x pounds

Weight gained by Baca in x weeks = 0.2x  pounds

Total weight of Luis after x weeks = (194 + 0.6x ) pounds

Total weight of Baca after x weeks = (218 + 0.2x) pounds

For Luis and Baca to be of the same weight,

Total weight of Luis after x weeks = Total weight of Baca after x weeks

Therefore, we equate the total weight gained by Luis and Baca after x weeks to determine the value of x

⇒ 194 + 0.6x  = 218 + 0.2x

⇒ 0.6x - 0.2x =218 - 194

⇒ 0.4x = 24

⇒ x = 60

Hence, Luis and Baca would be the same weight after 60 weeks of weightlifting.
