Answer:
D) -4x+14
Step-by-step explanation:
We are given with the expression
3 - (4x - 5) + 6
Here we are going to open the bracket at first step
as we have a negative sign in front of bracket the signs of the terms inside brackets will be reversed
3-4x+5+6
now we bring the like terms together
3+5+6 - 4x
Here 3, 5, 6 all are constant and hence like
14-4x
or
3 - (4x - 5) + 6= -4x+14
Hence our answer is -4x+14
Ann wants to choose from two telephone plans. Plan A involves a fixed charge of $10 per month and call charges at $0.10 per minute. Plan B involves a fixed charge of $15 per month and call charges at $0.08 per minute.
Plan A $10 + .10/minute
Plan B $15 + .08/minute
If 250 minutes are used:
Plan A: $10+$25=$35
Plan B: $15+$20=$35
If 400 minutes are used:
Plan A: $10+$40=$50
Plan B: $15+$32=$47
B is the correct answer. How to test it:
Plan A: $10+(.10*249 minutes)
$10+$24.9=$34.9
Plan B: $15+(.08*249 minutes)
$15+$19.92=$34.92
Plan A < Plan B if less than 250 minutes are used.
