Please help. On a winter day in Alaska, the temperature at noon was -0.6°C. From noon to 3:00, the temperature increased by 1.2°C. From 3:00 to 6:00, it dropped 0.4°C, and from 6:00 to 9:00, it decreased by 0.6°C. What expression shows the temperature in °C at 9:00 p. m.?
1. -0.6 + 1.2 + (-0.4) + (-0.6)

2. -0.6 + 1.2 – (-0.4 – 0.6)

3. -0.6 + 1.2 – (-0.4) – (-0.6)

4. 1.2 – (-0.4 – 0.6)

1st choice

Step-by-step explanation:

Temp at noon was -0.6. It increases 1.2 until 3.

-0.6+1.2

gets colder 0.4, then 0.6.

-0.6+1.2-0.4-0.6

the only correct way to put this equation as one of the other answers is by putting it as -0.6+1.2+(-0.4)+(-0.6)

hope that helped!

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.
