Step-by-step explanation:
This is a second order linear differential equation . Im afraid Ive forgotten the method. Any good calculus book would help with this.
Answer:
For each part, find how many numbers have the stated characteristic, then divide by 21.
e.g. multiples of 5:
these would be 10, 15, 20, 25, and 30
so prob (a multiple of 5 ) = 5/21
Do the others the same way
14) Since f=5, f + 69 = 74
15) Since w = 23, w + 45 = 68
Answer
The equation is already in slope intercept form so just graph it as you normally would.
Step-by-step explanation:
graph the -3x as a line the looks like this \ that goes through the +60. It should look like this
