Reflect over y-axis,reflect over the X axis ,rotate 180°

Option D is the correct option.

Explanation:

Let's take point A which is (4,-1)

Reflection over y- axis will make this point (4,1)

Then, reflection over X axis will make this point (4,-1)

After rotation of 180 degree we will get (-4,1) .

Please see the attached picture....

Hope it helps...

Good luck on your assignment...

Answer: d) reflect over the x-axis, reflect over y-axis, rotate 180°

Step-by-step explanation:

A reflection over the x-axis and a reflection over the y-axis is the SAME as a rotation of 180°. Together they make a rotation of 360°, which results in the image staying at the same place.

Reflection over the x-axis changes the sign of the y-coordinate

Z = (x, y) → Z' = (x, -y)

Reflection over the y-axis changes the sign of the x-coordinate

Z' = (x, -y) → Z'' = (-x, -y)

Rotation of 180° changes the signs of both the x- and y-coordinates

Z'' = (-x, -y) → Z''' = (x, y)

The set of points that represents a function is given by:

A {(2, 1), (7, 9), (3, 12), (4, 10)}.

<h3>When does a relation represents a function?</h3>

A set, or a relation, represents a function when each value of x is mapped to only one value of y.

In this problem, we have that option A represents a function, as:

In option B, x = 2 and x = -2 are mapped to two values.

In option C, x = 4 is mapped to four values.

In option D, both x = 1 and x = 2 are mapped to two values.

Hence the set of points that represents a function is given by:

A {(2, 1), (7, 9), (3, 12), (4, 10)}.

Dawn and abed each roll a standard die obtaining a random number from 1 to 6. if the probability that dawns number is larger tha

larisa [96]

Answer:

a+b = 12

Step-by-step explanation:

There are 36 possible outcomes for rolling two dice. Let A be the number rolled by Abed and D be the number rolled by Dawn. The sample space, in the format [A,D], of all of the possibilities in which Dawn's number is larger is:

[5,6]

[4,5] [4,6]

[3.4] [3,5] [3.6]

[2,3] [2.4] [2,5] [2.6]

[1,2] [1,3] [1.4] [1,5] [1.6]

There are 15 ways out of 36 possible ways of Dawn getting the higher number. In the simplest form:

$\frac{15}{36}=\frac{5}{12}=\frac{a}{b}\\ a+b = 5+12 = 17$
