Explain why the equation 6|x| + 25 = 15 has no solution. when one solves, they arrive at a step where |x| is equal to a negative number. since | x| can never be negative, there is no solution. when one solves, they arrive at a step where x is equal to a negative number. since x can never be negative inside of the absolute value bars, there is no solution. the statement is false. there is a solution. when one solves, they arrive at a step where |x| is equal to a fraction that may not be represented as an integer. since | x| must be an integer, there is no solution.

Step-by-step explanation:
6|x| + 25 = 15
6|x| = 15 - 25
6|x| = -10
|x| = -
By definition, the absolute value of any number must be positive, hence | x| can never be negative, there is no solution.

i would say independent since the problem doesn't state any relation between disease X and disease Y. Also I beleive if it were dependent the probability of getting both wouldn't be .494 (which is .65 *.76). It would have to be probability of event A and event B, and then divided by probability of just B
