Answer:
v = 12 km/h
Step-by-step explanation:
To find how much she should increase the speed first we need to find the distance traveled:
Where:
d: is the distance traveled =?
v: is the velocity = 8 km/h
t: is the time = 15 min (9:00 to 9:15)
Now, we can find the speed:

Therefore, she should increase the speed to 12 km/h to reach the office at 9:10 am.
I hope it helps you!
Answer:
(x) = 
Step-by-step explanation:
let y = h(x) and rearrange making x the subject, that is
y =
x + 12 ( multiply through by 4 to clear the fraction )
4y = 3x + 48 ( subtract 48 from both sides )
4y - 48 = 3x ( divide both sides by 3 )
= x
Change y back into terms of x, thus
(x) = 
The check that hasn't been cleared is the $82.75 check.
