Which transformation or combination of transformations can be used to show that quadrilateral jklm with vertices j(8, 4), k(4, 10), l(12, 12), and m(14, 10) is congruent to quadrilateral wxyz with vertices w(8, -4), x(4, -10), y(12, -12), and z(14, -10)? a. a reflection b. a rotation c. a reflection followed by a dilation d. a stretch followed by a reflection e. a rotation followed by a dilation

The correct answer is:

A. a reflection

Explanation:

Each point (x, y) in the pre-image is mapped to a corresponding point (x, -y) in the image.  Since only the value of the y-coordinate changes, this is a reflection through the x-axis.

a reflection

Step-by-step explanation:

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
