Mia records the distance traveled in x minutes in the table below, while Alexa uses a graph to record her distance traveled over the same time period. Alexa’s Graph A graph has time (minutes) on the x-axis and Distance traveled (miles) on the y-axis. A line goes through points (4, 3) and (8, 6). Mia’s Table A 2-column table with 4 rows. Column 1 is labeled Time (minutes) with entries 10, 18, 20, 26. Column 2 is labeled Distance Traveled (miles) with entries 5, 9, 10, 13. Based on the data on the graph and in the table, which statement gives an accurate comparison? Alexa traveled at a faster rate because the slope of her line is Three-fourths, which is greater than the slope of the line described by the data in Mia’s table. Alexa traveled at a faster rate because the slope of her line is Four-thirds, which is greater than the slope of the line described by the data in Mia’s table. Mia traveled at a faster rate because the slope of the line described by the data in her table is One-half, which is greater than the slope of the line on Alexa’s graph. Mia traveled at a faster rate because the slope of the line described by the data in her table is StartFraction 2 Over 1 EndFraction, which is greater than the slope of the line on Alexa’s graph.
Answer:

Which two lines must be parallel in the diagram?
Answer: j || k
Step-by-step explanation:
only j and k are explicitly shown to be 90 degrees, so they must be parallel since they have the same angle when intersected by line l.
Since ∠1 and ∠2 are corresponding angles and both have an equal measure, then j║k.
We need to check which lines from the given diagram are parallel.
What are different conditions to prove the given lines are parallel?Conditions to prove the given lines are parallel are as follows:
The first is if the corresponding angles, the angles that are on the same corner at each intersection, are equal, then the lines are parallel. The second is if the alternate interior angles, the angles that are on opposite sides of the transversal and inside the parallel lines, are equal, then the lines are parallel.Here, ∠1 and ∠2 are corresponding angles.
Thus, ∠1 =∠2=90°.
Since ∠1 and ∠2 are corresponding angles and both have an equal measure, then j║k.

Use the figure to find the measures of the numbered angles.
∠1 =
∘
∠2 =
∘
Step-by-step explanation:
The given angle is 107°;
Since the lines given are parallel and a transversal cuts them, angle 1 and 107° are corresponding angles.
Corresponding angles are equal;
So, ∠1 = 107°;
Now, ∠1 and ∠2 are angles on a straight line;
∠1 + ∠2 = 180°
107° + ∠2 = 180°
∠2 = 180° - 107° = 73°
Answer: <1= 107 <2=73
Step-by-step explanation: Zigzag method for <1
<1+<2=180

Triangle A B C is reduced to triangle A prime B prime C prime. Triangle A prime B prime C prime is closer to point O. Which statements are accurate about the dilation? Check all that apply. The dilation is a reduction. The scale factor is between 0 and 1. A is the image of A' Point O is the center of dilation. OB = BB'
Answer:
A B D
Step-by-step explanation:
options A, B, and D are correct. Those are:
The scale factor is between 0 and 1. The dilation is a reduction.Point O is the center of dilation.What is Scale?The ratio between a distance on a map and its actual distance on the ground is known as the map's scale. Since scale must vary throughout a map due to the curvature of the Earth's surface, this straightforward idea is made more difficult. This change makes the idea of size significant in two different ways.
Given, Triangle A B C is reduced to triangle A prime B prime C prime. Triangle A prime B prime C prime is closer to point O. For that we have to imagine a Dilation point.
So, Let "O" origin point is the dilation center for the given Triangles.
Since triangle A'B'C' is closer to the origin point thus the Scale factor will be less than 1 and Dilation will be reduced
Thus, option A is correct.
Since triangle A'B'C' is closer to the origin point thus the Scale factor will be less than 1
Thus, option B is correct.
Since it is a dilation thus A is not the image of A'
since the scale factor is not mentioned thus we can say that if OB = BB'
Therefore, options A, B, and D are correct.

The value of y which can be the solution of the inequality, are 2, 3, and 4
What is an inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given is an inequality, 2y ≤ 8,
For y = 2,
2 × 2 = 4
Therefore, the value of inequality is 4, and is a solution.
For y = 3,
2 × 3 = 6,
Therefore, the value of inequality is 6, and is a solution.
For y = 4,
2 × 4 = 8
Therefore, the value of inequality is 8, and is a solution.
For y = 5,
2 × 5 = 10,
Since, the value of inequality should be less than or equal to 8, and 10 is greater than 8, therefore, it is not a solution of the inequality.
Similarly, y = 6, is also not a solution of the inequality.
Hence, the value of y which can be the solution of the inequality, are 2, 3, and 4

c. [tex]tan\angle KDF = \dfrac{1}{\sqrt{3} }[/tex]
d. tan∠BCK = 1
e. The coordinates of the point g is (4, 4·√3)
Step-by-step explanation:
a. The trigonometric ratio for tan is given as follows;
[tex]tan\angle X = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length}[/tex]
Therefore, we have;
[tex]tan\angle FKG = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length} = tan(60^{\circ}) = \dfrac{sin(60^{\circ})}{cos(60^{\circ}) } = \dfrac{\dfrac{\sqrt{3} }{2} }{\dfrac{1}{2} } = \sqrt{3}[/tex]
b.
[tex]tan\angle BKG = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length} = tan(45^{\circ}) = \dfrac{sin(45^{\circ})}{cos(45^{\circ}) } = \dfrac{\dfrac{1 }{\sqrt{2} } }{\dfrac{1}{\sqrt{2} } } = 1[/tex]
c.
[tex]tan\angle KDF = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length} = tan(30^{\circ}) = \dfrac{sin(30^{\circ})}{cos(30^{\circ}) } = \dfrac{\dfrac{1 }{2 } }{\dfrac{\sqrt{3} }{2 } } = \dfrac{1}{\sqrt{3} }[/tex]
d. In right triangle, ΔBKC, ∠BCK = ∠BKC = 45°

e. The x-coordinate of the point g is 4
The y-coordinate of the point g is 4 × tan(60°) = 4·√3
The coordinates of the point g is (4, 4·√3).
