Sara-Mei is solving the equation 2x+3=4(x−3)−2x+1. Her steps are shown below. 2x+3=4(x−3)−2x+1
2x+3=4x−12−2x+1
2x+3=2x−11
2x−2x=−11−3
0=−14

Which of the following should Sara-Mei conclude from her result?

A. She has made an error in one of her steps.
B. She must continue solving the equation.
C. The equation she is solving has no solution.
D. The equation she is solving has infinitely many solutions.

What is the inverse of the function f(x) = 2x + 1?

Can someone me with this graph problem by the way i need to know the answers by today since this assignment is due ! !

Aking and his army will attempt to capture a fortress. the left and right flanks break off from the main group to attack the west and east guard towers. suppose the left flank has a 60% chance of success and the right flank has a 75% chance of success, independently of one another. if both flanks capture their respective targets, then the king has a 98% chance of successfully taking the fort. if, however, only the left flank captures its tower, the king has an 80% chance of success; if only the right flank succeeds, the king has a 50% chance. if both flanks fail, then the king's chance of capturing the fort drops to 20%. it turns out the king captures the fort. what is the probability that one, and only one, flank was successful (either the left, or the right, but not both)? (round your answer to 3 decimal places)
