What set of reflections would carry rectangle ABCD onto itself?

1 answer:

5 0

We are given a quadrilateral in the Cartesian coordinates whose vertex have the following coordinates:
A (-5,1)
B (-5,3)
C (-1,3)
D (-1,1)

For a set of reflection to result in the same image location and size, the image must be rotated 360 degrees. Among the choices, the only answer is
<span>y-axis, x-axis, y-axis, x-axis</span>

Shalnov [3]

Answer:176 psychology textbooks and 98 Biology textbooks were sold.

Step-by-step explanation:

Let x represent the number of psychology textbooks that were sold.

Let y represent the number of biology textbooks that were sold.

textbook store sold a combined total of 274 psychology and biology textbooks in a week. This means that

x + y = 274 - - - - - - - - - - -1

The number of psychology textbooks sold was 78 more than the number of biology textbooks sold. This means that

x = y + 78

Substituting x = y + 78 into equation 1, it becomes

y + 78 + y = 274

2y = 274 - 78

2y = 196

y = 98

x = y + 78 = 98 + 78

x = 176

Two figures are shown. EFJL is dialation of ABIK AB has a length of 12 and EF has a length of 3

Dimas [21]

The scale factor of dilation from AB to EF is 0.25

<h3>How to determine the scale factor of dilation?</h3>

The given parameters are:

EFJL is dilation of ABIK
AB has a length of 12
EF has a length of 3

From the above parameters, side lengths AB and EF are corresponding sides

This means that:

The scale factor of dilation (k) is

k = AB/EF

So, we have

k = 3/12

Evaluate

k = 0.25

Hence, the scale factor of dilation from AB to EF is 0.25
