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
Answer:

the second green shape because the first one is a rectangle which has 2 equal sides
Answer:

Step-by-step explanation:
To derive the function rule in slope-intercept form,
, we need to find the slope, m, and the y-intercept, b, of the graph given.
Using two points on the line, (-1, 2) and (0, -2), find slope (m) as shown below:

m = -4
The line intercepts the y-axis at y = -2, therefore the y-intercept, b, = -2.
Substitute m = -4, and b = -2 into
.
The function rule in slope-intercept form would be:
