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:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
