15. If l//m, find the measure of each angle.
If q ║ r, value of x is 17.
Define alternate exterior angle.When a transversal connects two or more parallel lines at different locations, alternate exterior angles are created. The word exterior refers to something that is located outside. Whenever the transversal intersects two lines, alternate external angles are always outside of those two lines and are situated on the opposing sides of the transversal. As a result, the pair of alternate external angles—two outside angles—that arise at the opposing ends of transversals in the exterior section are always equal. When a transversal splits two parallel lines, we obtain two of these pairs of alternate exterior angles.
Given
q ║ r
Alternate exterior angle,
7x - 10 = 9x - 44

Is reflection same as rotation 180 degrees?
Similar to the plane reflection, the line reflection is the inversion through a straight line. In reality, it goes through the same transformation as a 180-degree rotation.
What is reflection?A reflection is referred to as a flip in geometry.
A reflection is the shape's mirror image.
A line, called the line of reflection, will allow an image to reflect through it.
Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another. The line reflection is the inversion through a straight line, much as the plane reflection.
Actually, it undergoes the same change as a 180-degree rotation.
For this reflection, the rule would be written as RX-axis (x,y)→(x,y).
Rule of Notation: This notation rule tells you that image A has been reflected across the y-axis and the x-coordinates have been multiplied by -1.
It has the form by-axis A→B = axis (x,y)→(x,y).

The graph of inequality x < −2 is as shown below.
In this question we need to graph x is less than or equal to negative 2.
i.e., we need to graph an inequality x < −2
First we draw a straight vertical line x = -2.
The graph of x = -2 is a straight line parallel to y-axis and intersects x-axis at (-2, 0)
We represent the graph of x = −2 by the dashed line.
The dashed line indicates that the line is the boundary of the inequality but not part of it. Shade in the left side of the line to indicate the inequality x<−2.
Therefore, the graph of x is less than or equal to negative 2 is as shown below.

[tex]x^2+2x = (x+1)^2-1\quad[\because\, x^2+2x+1=(x+1)^2][/tex]

[tex]dx=\sec\theta\tan\theta\, d\theta[/tex]
[tex]\dfrac{d\theta}{dx}=\dfrac{1}{\sec\theta\tan\theta}\quad\dots(3)[/tex]
Then (1) becomes,
[tex]\longrightarrow g(x) = \sqrt{sec^2\theta-1}[/tex]
We have,

So we get,

By chain rule,
[tex]\longrightarrow g'(x) = \dfrac{d}{d\theta}\,[\tan\theta]\cdot\dfrac{d\theta}{dx}[/tex]

Answer:
a) 47
b) 61
Step-by-step explanation: We can setup two equations from the information given above:
2c + 4b = 14 where c is the cost if one carousel ticket and b is the cost of four bumper car tickets.
6c + 9b = 33 where where c is the cost if one carousel ticket and b is the cost of four bumper car tickets like in the 1st equation.
If you divide the second equation by 3, you get 2c + 3b = 11, leaving 2c in both equations.
If you subtract both equations by the elimination method:
2c + 4b = 14
-
2c + 3b = 11
---------------------------
b = 3, which solves for the cost of one bumper car ticket
If you plug this value back into the first (or second) equation,
ex. 2c + 4(3) = 14 -> 2c = 2 -> c=1
You get c = 1, which solves for the cost of one carousel ticket.
Then you plug these values (c=1 and b=3) in a) and b):
a) 8*1 + 13*3 = 47
b) 10*1 + 17*3 = 61
