A function is shifted vertically upwards/downwards by adding/subtracting a constant value to the function.
In this case f(x) was shifted upwards by 3 units.
Well, If the area of ABC is 20cm², Then the area of ABS would be 10cm² and the area of ACS would also be 10cm². You basically are just cutting the ABC in half. I hope this helps!
Answer:
7 minutes
Step-by-step explanation:
The scientist changes the temperature for the solution at a rate of -7°C per minute. We need to find out how long it'll take for the solution's temperature to change from 0°C to -49°C. So, we divide -7 by -49 to find out how long it will take:
-49 / -7 = 7
It will take 7 minutes for the temperature to reach -49°C.
