Jill ran faster. I know because I compared both of their unit rates.
Jack's unit rate is 5/42.5 = 0.118 mile per minute (rounded)
Jill's unit rate is 3/23.25 = 0.129 mile per minute (rounded)
Jill runs a greater part of a mile per minute than Jack does.
She is faster. There's no getting around it.
Next time please add answer choices
f(x) = y = x+3, Consider y=x+3. You just switch x and y:
so y= x+3, becomes x=y+3. Once done, you isolate y:
x=y+3 or y = x-3. This this the inverse function of f(x)
Answer:5
Step-by-step explanation:5/3 x 3/1= 15/3= 5
