A student is attempting to solve the equation below for the variable x Which of the statements below best applies to
the mathematical work shown?
Given x +5 = 1, 1 square both sides, which gives me the equation x + 5 = 1. I can then solve for x, yielding x = -4 as
my final answer.
A. The student did not correctly square both sides of the equation,
B. The student did not properly isolate the variable after squaring both sides of the equation,
C. The student omitted a negative solution to the equation,
D. The mathematical work is correct.

Christine wong has asked dave and mike to her move into a new apartment on sunday morning. she has asked them both, in case one of them does not show up. from past experience, christine knows that there is a 40% chance that dave will not show up and a 30% chance that mik a. what is the probability that both dave and mike will show up? (round your answer to 2 decimal places.) b. what is the probability that at least one of them will show up? c. what is the probability that neither dave nor mike will show up? (round your answer to 2 decimal places.)e will not show up. dave and mike do not know each other and their decisions can be assumed to be independent.
