Answer:

(x,y) ---> (-x,y)  2nd choice

Step-by-step explanation:

reflection: If points reflect across the y-axis, their y-coordinates remain unchanged but their x-coordinates change into their opposites.

The original figure ABCD is reflected on y-axis and we got the image A'B'C'D'. Therefore, option B is the correct answer.

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

In the given graph, ABCD is the original figure and A'B'C'D' is the image.

Here, A(-2, 1)→A'(2, 1)

B(-4, 1)→B'(4, 1)

C(-4, 5)→C'(4, 5)

D(-2, 4)→D'(2, 4)

Here, the rule is (x, y)→(-x, y)

Therefore, option B is the correct answer.

Answer:

59049 ways

Step-by-step explanation:

Given

[tex]Colors = 9[/tex]

[tex]Dogs = 5[/tex]

Required

Determine number of selection (repetition is allowed)

The number of collars is not given.

So, we'll assume that there are enough collars to go round.

If no repetition is allowed, each of the 5 dogs have 9 colours to select from.

i.e.

[tex]Dog\ 1 = 9[/tex]

[tex]Dog\ 2 = 9[/tex]

[tex]Dog\ 3 = 9[/tex]

[tex]Dog\ 4 = 9[/tex]

[tex]Dog\ 5 = 9[/tex]

So, the number of selection is:

[tex]Selection = 9 * 9 * 9 * 9 * 9[/tex]

[tex]Selection = 59049[/tex]

Answer:

- 2

Step-by-step explanation:

so in order to solve this equation we are going to have to add x to each side of the equal sign to make the x a positive:

-6 - x = -4

    + x     + x

making the equation look like this:

-6 = -4 + x

Now we are going to add 4 to each side of the equation to segregate our x:

-6 = -4 + x

+4   + 4

Making the equation look like this:

-2 = x

Now to check our work by placing -2 where x is in the equation -6 - x = -4:

-6 - x = -4 now -6 - (-2) = -4

Since the negative number is next to a subtraction sign -2 becomes positive 2

-6 + (2) = -4

We add them together and....:

-4 = -4

Answer: Your answer would be A. A full on explanation is the denominators both have to be equal so 24 is right then you factor and multiply the numerator by how ,uch it takes the denominator to get to 24. So 2 20/24 + 3/24 is 2 23/24. I hope this helps you. Your answer is A = 2 23/24

Answer: r=4b/m-k

Step-by-step explanation: I think

The solution of the given formula B=1/4m(r + k) for r is r = 4(B/m) - k.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.

Given the expression,

B=1/4m(r+k)

4B = m(r + k)

r + k = 4B/m

r = 4(B/m) - k

Hence "The solution of the given formula B=1/4m(r + k) for r is r = 4(B/m) - k".

A) Olivia's spinner has the highest probability of spinning purple.

The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.

Given:

Olivia and Cody both have spinners with the color purple.

Olivia determines that the probability of spinning purple on her spinner is 4 out of 12.

That means, 4/12 = 0.33

Cody determines that the probability of spinning purple on his spinner is 3 out of 10.

That means, 4/10 = 0.3

0.33 > 0.3

Therefore, Olivia's spinner has the highest probability of spinning purple.

Answer:

$360

Step-by-step explanation:

I = Prt

I = 4000 * 3 * 3%

I = 12000 * 3% (Convert 9000 and 3% into fractions.)

I =12000/1 * 3/100 (100 and 12000 have a GCF of 100)

I = 120/1 * 3/1 (Disregard the over 1 portion.)

I = 120 * 3 (Multiply 120 by 3 to get 360.)

I = $360

Answer and Step-by-step explanation:

The square root of 16 times x to the power of 6 times y to the power of 10 is the same as:

[tex]\sqrt{16x^{6} y^{10} } = \sqrt{16} * \sqrt{x^{6} } * \sqrt{y^{10} }[/tex]

The square root of 16 is 4.

The square root of x to the power of 6 is x to the power of 3.

The square root of y to the power of 10 is x to the power of 5.

So, the answer is:

[tex]4x^{3} y^{5}[/tex]
