Answer:
-3 <x <-1
Step-by-step explanation:
|x + 2| < 1
There are two solutions, one positive and one negative ( remember to flip the inequality for the negative)
x+2 <1 and x+2 > -1
Subtract 2 from each side
x+2-2 < 1-2 and x+2-2 > -1-2
x < -1 and x >-3
-3 <x <-1
Answer:
The first one is: 5x (x+3)
second one: 6x+13-(-7x)
Step-by-step explanation:
The question is about rearranging the given formula to express M in terms of T,C and N:
If you subtract CN on the left and on the right, then swap it around, you get:
M = T - CN
Which is the rewritten formula for M. (Check if it makes sense: the total cost minus the monthly cost is the remaining yearly membership cost, yes that does make sense).
