What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
The quadrilateral JKLM is shown in the given figure.
As per the given graph, we can see that
The coordinates of M would be : (4, 1)
Suppose quadrilateral J´K´L´M´ is a reflection of JKLM in the line y = x.
Then the coordinates of M´ would be : (4, 1)
The coordinates of J would be : (1, 3)
Suppose quadrilateral J''K''L''M'' is a rotation of JKLM 90° counterclockwise about the origin.
Under a counterclockwise rotation about the origin of 90 degrees
A coordinate ( x, y ) → ( y, - x ),
The coordinate J is (1, 3) and is translated using the rule
Then simply plug in the values of x and y which are x = 1 and y = 3
Thus (1, 3) → (3, -1)
Thus, the coordinates of J'' would be : (3, -1)

Answers
The equations equivalent to 2.3p – 10.1 = 6.5p – 4 – 0.01p are;
2.3p – 10.1 = 6.49p – 4 230p – 1010 = 650p – 400 – pThe correct answer is option B and C
How to determine equivalent equation?2.3p – 10.1 = 6.5p – 4 – 0.01p
collect like terms
2.3p - 6.5p + 0.01p = -4 + 10.1
-4.19p = 6.1
p = 6.1/-4.19
p = -1.46
2.3p – 10.1 = 6.5p – 4 – 0.01p
= 2.3p – 10.1 = 6.49p – 4
Given options:
2.3p – 10.1 = 6.4p – 4
False
2.3p – 10.1 = 6.49p – 4
True
230p – 1010 = 650p – 400 – p
divide through by 100
= 2.3p – 10.1 = 6.5p – 4 – 0.01p
True
23p – 101 = 65p – 40 – p
False
2.3p – 14.1 = 6.4p – 4
False
Therefore, 2.3p – 10.1 = 6.49p – 4; 230p – 1010 = 650p – 400 – p are equivalent to 2.3p – 10.1 = 6.5p – 4 – 0.01p.

Answers
The probability of both events occurring is P(A ∩ B) = P(A)P(B) = 0.16^2 = 0.0256.
The event of getting a "2" and the event of getting a "5" on the first roll of a die are mutually exclusive events because they cannot both occur in the same trial. The probability of either of these events occurring is P(A) = 0.16, and the probability of both events occurring at the same time is P(A ∩ B) = 0.00.
The event of getting a "2" on the first roll and the event of getting a "5" on the second roll of a die are independent events. This can be confirmed using the formula P(A ∩ B) = P(A)P(B). The probability of getting a "2" on the first roll is P(A) = 0.16 and the probability of getting a "5" on the second roll is P(B) = 0.16.

Answers
Answer:
Step-by-step explanation:
if x were starting at 0, we would have
y = (x - 7)×7 = 7x - 49
but we start at x = 57. We need adjust for these extra 57 to get the above equation.
so, it
y = (x - 57 - 7)×7 = (x - 64)×7 = 7x - 448
so, for
y = (x - 64)×7
I choose x = 57
y = (57 - 64)×6 = -7×7 = -49
for
y = 7x - 448
I choose x = 58
y = 7×58 - 448 = 406 - 448 = -42
from this form we get the y-intercept (the y- value when x = 0) : -448

What is the additive inverse of 2 /- 7?
Answers
The additive inverse of 2 /- 7 is -2 /+ 7.
An additive inverse is a number that when added to the number in question, the sum is equal to zero. This can be expressed by the formula x + (-x) = 0, where x is the number in question. In this case, x is 2 /- 7. So, when 2 /- 7 is added to its additive inverse, -2 /+ 7, the sum is 0. This can be expressed mathematically as 2 /- 7 + (-2 /+ 7) = 0. Calculating this equation, we get 2 /- 7 + (-2 /+ 7) = -2 /+ 7 + (-2 /+ 7) = -4 /+ 14 = 0. Therefore, the additive inverse of 2 /- 7 is -2 /+ 7.

The graph of a function is a visual representation of the relationship between the input values (x-coordinates) and the output values (y-coordinates) of the function. In other words, it is a visual representation of the function's rule.
The graph of a function can take many different forms, depending on the function's rule. Linear functions, for example, will produce a straight line on the graph.
i) 2y - 4x < 8 can be solved by adding 4x to both sides and then dividing by 2, giving:
y < 2x + 4.
ii) -4y > -x + 12 can be solved by adding x to both sides and then dividing by -4, giving: y < x/4 - 3.
iii) | x + 3 | = y, you can split this into two cases:
i. x + 3 = y
ii. -(x + 3) = y
iv) |2x – 6| + 2 = y, you can split this into two cases:
i. 2x - 6 + 2 = y
ii. -(2x - 6) + 2 = y
We can use these equations to plot the graph on a coordinate plane.

A data set is a grouping of data. A data set refers to one or more database tables in the case of tabular data, where each column of a table represents a specific variable and each row corresponds to a specific record of the data set in question.
Given that,
the number of points scored in the last basketball game by each player on the Dragons basketball team are 7, 5,8,11,7,5,?.
Assume that the missing point is x.
The sum of points is 7+5+8+11+7+5+x = 43 + x.
The number of points is 7.
The mean is the sum of points/number of points

Answers
We calculate the percentage of black paint in each mix by dividing the amount of black paint by the total amount of paint and multiplying by 100. Julian's mix has a black paint percentage of 52.94% while Harper's mix has a black paint percentage of 58.33%. Therefore, Harper's gray paint will be darker.
Explanation:The first step to determine whose gray paint will be darker is to calculate the percentage of black paint each student has in their mix. To find this, one must know that the percentage is calculated by dividing the part (the quantity of black paint) by the whole (the total amount of paint) and then multiplying by 100.
Julian's percentage of black paint: (9 cups black / 17 total cups) * 100 = 52.94%
Harper's percentage of black paint: (7 cups black / 12 total cups) * 100 = 58.33%
Since the percentage of black paint correlates with the darkness of the gray paint, Harper's gray paint will be darker because it contains a higher percentage of black paint.
