-4(3m-3)+(-10+8m)
12m+12-1+8m
12m+8m = 20m
+12 -1= +11
answer: 20m+11
*note negative times a negative equals positive and negative times positive is negative
first: you multiply -4 by 3m which is -12m.
second: you multiply -4 by -3 which is +12
third: find the invisible which is 1. (located right here: +(1) (-10+8m)
fourth: multiply invisible 1 by -10 which is -10
fifth: multiply invisible one by +8m which is +8m
sixth: combine like terms
seventh: answer
Answer:
im here for the points sorry
Step-by-step explanation:
Answer:
-170= -10m - 20
Step-by-step explanation:
-20 is the y intercept, so in the equation y=mx+b that would be the b. Because he is going down at 10 meters per minute, it means that the -10 would go into the x spot and the -170 is where he needs to get to. Hope this helped!
