B. reflection across the y-axis
C. reflection across y = x
D. reflection across y=−x
Answer:
→△ABC is reflected to form △A′B′C′ .
→→Vertices of △ABC are A(-1, 3) , B(2, 4) , and C(-5, 6) and the vertices of △A′B′C′ are A′(3, −1) , B′(4, 2) , and C′(6, −5) .
Drawing the two images of ΔABC and ΔA'B'C'on two Dimensional Coordinate Plane
When, reflection takes place,the two, Image, and Pre-Image are Congruent, that is neither the shape nor the Size changes only translation of the shape takes place on the coordinate plane.
Option C: → Reflection across y = x.
Answer:
C. reflection across y = xStep-by-step explanation:
The given transfomation is
[tex]A(-1,3) \implies A'(3,-1)\\B(2,4) \implies B'(4,2)\\C(-5,6) \implies C'(6,-5)[/tex]
Notice that the rule of the given transformation is
[tex](x,y) \implies (y,x)[/tex]
That is, the coordinates were change of position, like an inverse.
According to transformation rules, this represents a reflection across the line [tex]y=x[/tex].
Therefore, the right answer is C.
A number cube has sides numbered 1 through 6. The probability of rolling a 2 is 16 .
What is the probability of not rolling a 2?
Enter your answer as a fraction, in simplest form, in the box.
Answer: The probability of not rolling a 2 is [tex]\dfrac{5}{6}.[/tex]
Step-by-step explanation: Given that a number cube has sides numbered 1 through 6. And the probability of rolling a 2 is [tex]\dfrac{1}{6}.[/tex]
We are to find the probability of not rolling a 2.
Let, 'A' denotes the event of rolling a 2.
So, we have
[tex]P(A)=\dfrac{1}{6}.[/tex]
The event of not rolling a 2 is given by the complement of event A.
The probability of the complement of event 'A' can be calculated as
[tex]P(A')=1-P(A)=1-\dfrac{1}{6}=\dfrac{5}{6}.[/tex]
Thus, the probability of not rolling a 2 is [tex]\dfrac{5}{6}.[/tex]

What is the greatest common factor of 20y^9 + 5y^6 ?
A. 5y^9
B. 20y^3
C. 5y^6
D. 10y^9
The greatest common factor of 20y^9 + 5y^6 is 5y^6.
Explanation:To find the greatest common factor (GCF) of 20y^9 + 5y^6, we need to determine the highest power of each variable that divides each term evenly. In this case, the highest power of y that can be divided evenly is y^6. The GCF of the two terms is therefore 5y^6.

The tables below show four sets of data: Set A x 1 2 3 4 5 6 7 8 9 y 10 9 8 7 6 5 4 3 2 Set B x 1 2 3 4 5 6 7 8 9 y 3 4 5 6 7 8 9 10 11 Set C x 1 2 3 4 5 6 7 8 9 y 8 6 5 4 3.5 3 2.5 2 2 Set D x 1 2 3 4 5 6 7 8 9 y 1 2.5 2.5 3 4 5 6 8 9 For which set of data will the scatter plot represent a positive nonlinear association between x and y? (1 point) Set A Set B Set C Set D
The set C shows a positive nonlinear association between x and y
How to determine the set that shows a positive nonlinear association between x and y?The set is given as:
Set A
x 1 2 3 4 5 6 7 8 9
y 10 9 8 7 6 5 4 3 2
Set B
x 1 2 3 4 5 6 7 8 9
y 3 4 5 6 7 8 9 10 11
Set C
x 1 2 3 4 5 6 7 8 9
y 8 6 5 4 3.5 3 2.5 2 2
Set D
x 1 2 3 4 5 6 7 8 9
y 1 2.5 2.5 3 4 5 6 8 9
For the set to represent a non linear association, then the variables increases or decreases as the other variable changes but the direction must form a curved pattern.
Sets A, B and D are linear asociation because the output variables increases or decrease as the input variable increases
Hence, the set C shows a positive nonlinear association between x and y

identify each angle pair as adjacent, vertical, or neither...?
Write an equation that you can use to solve for x. Enter your answer in the box. Two lines intersect at a point, forming two adjacent angles. One adjacent angle is labeled x degrees and the other adjacent angle is labeled 47 degrees.
Answer: The value of x is 133°.
Step-by-step explanation:
Since we have given that
Two lines intersect at a point forming two adjacent angles.
Measure of one adjacent angle is labeled as = x degrees
Measure of other adjacent angle is labeled as = 47 °
We need to find the value of x in degrees.
As shown in the figure:
Since they are adjacent angles.
So, we can write it as
[tex]x+47^\circ=180^\circ\\\\x=180^\circ-47^\circ\\\\x=133^\circ[/tex]
Hence, the value of x is 133°.
A scientist is measuring the amount of radioactive material in an unknown substance. When he begins measuring, there are 56.8 grams of radioactive substance. Twelve days later, there are 55.45 grams. After 25 days, there are 54.03 grams. After 41 days, there are 52.32 grams. Assuming that the decay is exponential, find the equation that determines the number of grams remaining after x days and use the equation to determine the amount of radioactive material remaining after 500 days.

a number multiplied by -8, subtracted from the sum of 14 and five times the number
Let us suppose the number is x. Now we try to make an algebraic expression going step by step.
Step 1:
Five times the number means 5 multiplied by x.
So it becomes 5x.
Step 2:
Sum of 14 and five times the number means 5x+14.
Step 3:
Number multiplied by -8 means -8x.
Step 4:
Subtract the expression in step (3) from expression in step (2)
5x+14-(-8x)
Now we can simplify it further,
5x+14+8x
Combining like terms,
13x+14
Answer: The final expression becomes 13x+14.

Which events are mutually exclusive? Check all that apply.
landing on a shaded portion and landing on an even number
landing on a shaded portion and landing on a number greater than 3
landing on a shaded portion and landing on a 3
landing on an unshaded portion and landing on an odd number
landing on an unshaded portion and landing on a number less than 2
Answer:
landing on a shaded portion and landing on an even number ; landing on a shaded portion and landing on a number greater than 3 ; landing on an unshaded portion and landing on an odd number ; and landing on an unshaded portion and landing on a number less than 2.
Explanation:
Mutually exclusive events are events that cannot occur at the same time. Our spinner has two grey sections, on 1 and 3; and two white sections, on 2 and 4.
This means that the spinner cannot land on a shaded (grey) portion and land on an even number at the same time, since the grey sections are numbered 2 and 4, both of which are even numbers.
The spinner also cannot land on a shaded (grey) portion and land on a number greater than 3 at the same time; this is because the only number greater than 3 on the spinner is 4, which is a white portion.
The spinner cannot land on an unshaded (white) portion and land on an odd number, since the white sections are labeled 2 and 4, which are both even.
The only number on the spinner less than 2 is 1, which is grey; this means the spinner cannot land on a number less than 2 and an unshaded (white) portion at the same time.
