I think that the answer is 3Y+30. I hope this helps!!! :)
I am pretty sure is 70 degrees but I don’t know for sure
Answer:
The answer to your question is the last option
Step-by-step explanation:
Process
1.- To calculate the rate of change, calculate slope
Formula
m = (y2 - y1) / (x2 - x1)
x1 = 1 y1 = 1200
x2 = 2 y2 = 2400
2.- Substitution
m = (2400 - 1200) / (2 - 1)
3.- Simplification
m = 1200 / 1
4.- Result
m = 1200 meters / minute
First off you need to convert the numbers into mixed numbers.
1 3/7 goes to 10/7
3 2/3 goes to 11/3
Then you multiply the numerators together:
10 * 11 = 110
Do the same for the denominators:
3 * 7 = 21
Then place it into a fraction and you make the fraction positive because the signs at the start are the same:
110/21
Then you can turn it into a proper fraction:
5 5/21
