Answer:
The answer would be B. decrease the temperature by 2 degrees Celsius.
Step-by-step explanation:
Since 2°C - 2°C= 0, then you would obviously have to subtract to find your answer.
Answer:
It should be y=-1/2+(-1)
Step-by-step explanation:
You are looking for a number that, when multiplied by the same number, equals 30. This is can be written as x times x, or
= 30. To find the answer, all you have to do is take the square root of 30.
is approximately 5.477
Y=2x +4 is non proportional because b does not equal 0
The b in the equation is 4
As long as the y intercept is not more or less than 0, than it will be proportional
