1. Triangle ABC is dilated by a scale factor of 1.5 to create triangle A'B'C'. Which of
the following it not a true statement?
Answers
Answer:
d
Step-by-step explanation:
because it gets bigger so they are not going to have the same measures or lenghts.
The statement that is not true about the dilation is (c) the segment AB is congruent to the segment A'B
How to determine the false statement?When a shape is dilated, the orientation of the shapes is preserved but the side lengths of the shapes are not congruent
This means that the side lengths of triangle A'B'C are not congruent to triangle A'B'C
Hence, the statement that is not true about the dilation is (c) the segment AB is congruent to the segment A'B

A coach calculated the mean and the mode of the number of points scored by 6 players.
• mean: 7 points
mode: 8 points
How many points did player 5 score?
Answers
Because 8+8+8+6+7+5=42
Then divide that by 6 to get the mean - so 42/6=7 so that’s the correct mean
Explanation:
Mean = average
Equation: total points scored/total players
Mean=7+8+6+8+?+8/6
The mean is given: 7
So plug it in:
7=(7+8+6+8+?+8)/6
Factor to solve:
Add all the numbers together to leave just the missing number (?)
7=(37+?)/6
To get rid of the 6 multiply it over to the other side
6x7=37+?
42=37+?
Now subtract the 37 to the other side to find the missing number (?)
42-37=?
5=?
Now let’s check:
7+8+6+8+(5)+8=42
Add:
42
Now divide by 6
42/6=
7
Is 7 the mean they gave us? Yup!
So player 5 scored 5 points

A group of seventh graders and a group of teachers at a local middle school were asked how many siblings they each have. The dot plots below show the results. Students A dot plot titled Students. A number line going from 0 to 9 labeled number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9. Teachers A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9. When comparing the shape of the two sets of data, what conclusion can someone draw? The students tend to have fewer siblings than the teachers. The teachers tend to have fewer siblings than the students. Both the students and the teachers have a wide range of siblings. Both sets of data have the same shape. the answer is- a. The students tend to have fewer siblings than the teachers.
Answers
Answer:
A. The students tend to have fewer siblings than the teachers.
Step-by-step explanation:
First we need to draw the dot plots correctly. If you count both sides they have 20 each.
Now, clearly none have fewer nobody here yet has more or less but going on to the next step.
Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14. And so on.
On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.
So the answer is A. The students tend to have fewer siblings than the teachers.

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
Answers
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Angle 5 and Angle 7
Angle 1 and Angle 10
Angle 14 and Angle 16
Angle 7 and Angle 11
Answers
The two angles must be supplementary with angles 6 will be angle 5 and 7.
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
⇒ 4 lines intersect to form 16 angles.
And, The angles created, clockwise from top left are 1, 2, 3, 4; 5, 6, 7, 8; 13, 14, 15, 16,
Here, two combinations of angles 5 and 7 are having a sum of 180 degrees with angle 6.
So, The supplementary angles to angle 6 are angle 5 and angle 7.
Thus, The two angles must be supplementary with angles 6 will be angle 5 and 7.

-6x-2y=-14 determine the slope
Answers
Answer:
slope= -3
Step-by-step explanation:
-6x-2y=-14
+2y (to both sides)
-6x=-14+2y
+14 (to both sides)
-6x+14=2y
/2 (divide both sides by 2)
-3x+7=y
the slope is -3
y=mx+b (it’s the formula)
m is the slope. And b is intercept
-2y=6x-14
-y=3x-7
y=-3x+7
So the intercept (b) is 7

For a dilation centered at the origin with a scale factor of 3/2:
(a) original coordinates → final coordinates
R (-4,6) → R' (-6,9)
S (6,2) → S' (9,3)
T (-6,-4) → T' (-9,-6)
(b) (x, y) → ((3/2)x, (3/2)y)
How to determine a dilation mapping?To determine a dilation mapping, follow these steps:
Identify the center of dilation. This is the fixed point around which the dilation occurs.Determine the scale factor. The scale factor determines how much the image is stretched or shrunk. It can be a positive or negative number, but it cannot be zero.Apply the scale factor to each coordinate. To do this, multiply each coordinate by the scale factor, with the center of dilation as the origin.For example, if the center of dilation is (2, 3) and the scale factor is 2, the dilation mapping can be expressed as:
(x, y) → (2(x-2), 3(y-3))
This means that every point (x, y) is transformed into the point (2(x-2), 3(y-3)) after the dilation.
