How do you reflect over y axis

Mathematics

Think of a point not on the y-axis.
For example, think of the point (5, 5).
This point is in quadrant 1, right of the y-axis and above the x-axis.
To reflect it over the y-axis, the reflection will be in quadrant 2, still above the x-axis, but now left of the y-axis. The distance the reflection is from the y-axis is the same as the original point is from the y-axis.

The reflection of (5, 5) over the y-axis is (-5, 5).

To reflect any point over the y-axis, replace the x-coordinate with the additive inverse of the x-coordinate.

If you want to reflect over the y axis then your answer would want to be going either from the left side to the right side, or right side over to the left side. If the figure was on the top or bottom you would go over the x axis.

So to reflect over the y axis you must find the points that each angle or corner of the figure your reflecting. You'll want to remember those locations of the points, then you'll transfer them over to the other side on the same points but on the other side. I'll make an example to make it more clear

For the first number, before the coma, if the number is negative you'll go left, if the number is positive you go right
For the second number, after the coma, you go up if it's positive or down if its negative.

If A is located at (-3, +2)
Angle B at (-1, +2)
Angle C at (-2, +0)

To transfer them over the y axis the numbers being positive or negative will change
For example

Angle A will become (+3, +2)
Angle B will become (+1, +2)
And angle C will become (+2, 0)

If the number is zero then it stays on the default line.

Hope this helped,reply if you need more help!!

bulgar [2K]

Answer:

Animal books make up (3/20) of all books

Step-by-step explanation:

Let X be the total number of books, made up of nonfiction, animal, and all others.

(3/5)X are nonfiction books.

Of the nonfiction books, 1/4 are animal books:  (3/5)*(1/4)X = (3/20)X are animal books

[This means that Nonfiction, less animal books is:  (3/5)X - (3/20)X]

Animal books make up (3/20) of all books.

1. Using your straightedge, draw a reference line, if one is not provided.
2. Copy the side of the square onto the reference line, starting at a point labeled A'.
3. Construct a perpendicular at point B' to the line through ab2.
4. Place your compass point at B', and copy the side of the square onto the perpendicular b'g. Label the end of the segment copy as point C.
5. With your compass still set at a span representing AB, place the compass point at C and swing an arc to the left.
6. Holding this same span, place the compass point at A' and swing an arc intersecting with the previous arc. Label the point of intersection as D.
7. Connect points A' to D, D to C, and C to B' to form a square.

Alex Ar [27]

Answer: 29 = 5/6

Step-by-step explanation:

first you would convert 1 2/3 into a improper faction. So you would multiply 1 and 3  then add 2 so 5/3 then multiply that by 1/2. You would multiply the numerators and denominators, so 5 times 1 and 3 times 2 which gives you 5/6.

5x + 4 = 7x i need help quick
anyanavicka [17]
5x + 4 = 7x

Subtract 4 from both sides.

5x = 7x - 4

Subtract 7x from both sides.

5x - 7x = -4

Simplify.

-2x = -4

Divide both sides by -2.

x = 4/2

x = 2

~Hope I helped!~
