i honestly looked at the numbers in the problem
Sally is 6 and Tomas is 3 so
6 +(3×2)
and 6-3
Since the slope is -2, then m=-2. Since the y-intercept is 5, b=5. Then, we can create the equation: y=-2x+5
Since the slope is
, then m=
. Since the y-intercept is -3, b=-3.
Then, we can create the equation: y=
x-3
Answer:
160:340
Step-by-step explanation:
The hours between 2:00pm and 4:00pm is 2 hours. If originally 350 freshman and 200 sophomores are at the carnival, and 20 freshman leave every hour, we can determine how many freshman left in 2 hours:

and if 35 sophomores arrive every half our, we know that for every two hours there is 4 half hours, therefore:

The amount of freshman at 4:00pm:

and the amount of sophomores:

the ratio is 160:340
