A series of transformations maps EFGH onto its image. Determine the series of transformations involving a reflection, translatio
Annette [7]

Answer:

See below

Step-by-step explanation:

Firstly, we'll dilate EFGH by any scale factor.

<u><em>Let's find the scale factor first.</em></u>

=> Scale Factor = \frac{Side \ of \ dilated \ figure}{Side \ of \ original \ figure}

=> Scale Factor = \frac{6}{4}

=> Scale Factor = 1.5

1) Dilate the figure by a scale factor of 1.5

2) Reflect it across the origin

3) Translate (Move) 5 units down and then 10 units left.

These transformations will map EFGH onto its image.

Job A: $15.00 per hour (40 hours a week)​​Job B: $1,375 semi-monthly
blagie [28]

Notes before we start:

Semi-monthly means you get paid twice a week. We will find out the net pay in 2 weeks to see how much pays better.

Explanation:

Job A pays $15 an hour and whoever is working works 40 hours a week. We can multiply to find how much he/she earns in 2 weeks.

15 * 40 * 2 = $1,200

Job B pays $1,375 semi monthly which means that he/she got paid that much money in 2 weeks.

Answer:

Job B pays better.

Best of Luck!
