To find the average change per hour, divide the total change by the total time:
-9.9 inches / 2.25 hours = -4.4 inches per hour.
The LCM of two given numbers will be greater. For example, a factor is the two numbers multiplied together to get that certain m=number that you chose, which is usually pretty less, than the LCM is the multiple of those certain numbers, and if you put those together the answer to the factors (multiples) are most larger than the factors itself.
Answer: y=-2x+9
Step-by-step: Subtract 2x from 2x+y=9 and get y=-2x+9
B. (k+10f)(k-5f) you can tell in 2 ways. 1. if the second sign is neg then the signs in the factors are going to be one neg and one positive so that knocks out C and D. Then you look at the second term and since the 5 is positive then the 10 has to be positive so you end up with a positive 5kf.
The second way is to FOIL them out. When you check B you get
combine your like terms and you have your original expression of
