The train station clock runs too fast and gains 7 minutes every 4 days. How many minutes and seconds will it have gained at the end of 9 days

15 minutes 45 seconds.

Step-by-step explanation:

The train station clock runs too fast and gains 7 minutes every 4 days.

For 1 day, the clock gains = 1.75 minutes.

For 9 days the clock gains;

1.75 × 9 = 15.75 minutes

1 minute = 60 seconds

0.75 of a minute is equivalent to;

0.75 × 60 = 45 seconds

Hence the clock will have gained 15 minutes and 45 seconds after nine days.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
