I need it now a reflection across the y-axis followed by a reflection across the x-axis maps parallelogram ABCD onto parallelogram A'B'C'D'.

Select all of the true statements.

I Need It Now A Reflection Across The Y-axis Followed By A Reflection Across The X-axis Maps Parallelogram

Answers

Answer 1

Answer:

true statements:

- A'B' is parallel to C'D'

- the area of parallelogram ABCD is equal to area of A'B'C'D'

- the perimeter of ABCD is equal to the perimeter of A'B'C'D'

btw just so u understand the work i have shown above:

- the green parallelogram is the original one before any work was done

- the blue one was after it was reflected across the y-axis

- and the brown one was after the blue parallelogram was reflected across the x-axis

sorry if that was a confusion... i forgot to add it above im really sorry

but apart from that, hope u understand and get an A :))

|120+x| x<-120

Answers

Answer:

-120-x

Step-by-step explanation:

Given:

[tex]\displaystyle \large{|120+x| \quad (x < -120)}[/tex]

This is the same as previous one. Recall modulus property:

[tex]\displaystyle \large{|a+x| = \begin{cases} a+x \quad (x \geq -a) \\ -a-x \quad (x < -a) \end{cases}}[/tex]

Keep in mind that |x+a| and |a+x| are equal via addition property.

Since the question gives interval of x < -120:

Therefore, the expression is -120-x

what is the value of y when: -5=y-7over 9

Answers

Answer:

y=-38

Step-by-step explanation:

Undo the things that are being done to the variable.

1: Multiply both sides by nine to undo division.

-45=y-7

2: Add 7 to both side to undo the subtraction.

-38=y

Thats your answer!

Answer:

the answer should be -38 which is option c.

Step-by-step explanation: To get the answer first of all try a number that could be -7 -7 which would be -14 dividing by 9 making the results to be  -1.55 or -1.56. So using the same steps trying to find the other answers what is the value of y and if you want use the process of elimination choosing an answer to eliminate and a reason why to eliminate it making it to option c which is the correct answer so sorry if i answer late and please give brainliest to the other people that answer first.

Answer:

N=1

Step-by-step explanation:

If N = 1 then  4(1)= 4 whitch is less than 11

But if you plug in any other number

4(4) = 16

4(9) = 36

4(11) = 44

you can see that all of these are greater than 11, but we need something that is less than which would be N=1

first, divide both sides by 4 to get 2.75>n

this means n has to be less than 2.75

the only answer less than that is 1

so, n = 1

Step-by-step explanation:

when you count from point (0,-3) where the line perfectly intersects that point, to point (4,2) where it does the same, you end up having to go up 5 lines, and over 4 lines giving you your slope that goes movement on the y-axis over movement on the x-axis or y/x, and you calculate this without diagonals, and you jump before you walk in this case instead of walking before you jump.

Answer:

Question 1: 34.56 mm

Question 2: 12.57 in

Question 3: 15.70 yd

Step-by-step explanation:

Answer:

10. 91.08mm

11. 33.12in

12. 41.4yd

Step-by-step explanation:

To find the answer to each, we first need to calculate the circumference:

(use 3.14 for π)

(2 * Diameter) * π = Circumference

Then half the circumference (because it is a semicircle) and add it to the diameter once again to accommodate for the middle line.

(Circumference / 2) + Diameter

Do this for each semi-circle as shown here:

10. (2 * 22) * 3.14 = 138.16

(138.16 / 2) + 22 = 91.08

11. (radius is given so double the middle)

(2 * (2 * 4)) * 3.14 = 50.24

(50.24 / 2) + 16 = 33.12

12. (2 * 10) * 3.14 = 62.8

(62.8 / 2) + 10 = 41.4

A number cube is rolled 120 times. The number 4 comes up 47 times. What is the experimental probability of rolling a 4? What is the theoretical probability of rolling a 4?

Answers

Experimental: 47/120
Theoretical is 50/120

Answer:

OPTION B

B. [tex]\frac{47}{120} ; \frac{1}{6}[/tex]

Step-by-step explanation:

A number cube is rolled 120 times; The number 4 comes up 47 times.

First, we have to determine the experimental probability of rolling a 4.

The formula to evaluate probability of an event is given; Probability = [tex]favorable outcomes/totaloutcomes[/tex]

Probability of rolling a 4; the total number of times when 4 appears/the total number of times number cube rolled= [tex]\frac{47}{120}[/tex]

We have to find the theoretical probability of rolling a 4.

Total number of outcomes number cube; 1,2,3,4,5,6

Probability of rolling a 4; [tex]\frac{1}{4}[/tex]

OPTION B IS CORRECT
