Answer:
Step-by-step explanation:
For the sake of clarity, assuming you meant:
1) Absolute Value or Modulus functions has one property that assures us that:
2) Solving for x
Not defined in Real Set of Numbers
Evaluating :
3) So, since for the first case the Discriminant Δ <0, then the solutions presented for . The only solution in the Real Set for the inequality is , i.e. x=-1.
Based on the given details you have given, the total amount of money that you will have will be measured in dollars ($). Since the given value is also in dollars which is $2, therefore, the total amount of money you will have is also in dollars which is 250 x $2 is $500 in total. Hope this answers the question.
Answer:
i believe it would increase by 1
Step-by-step explanation:
Percent error is calculated by the know amount minus the amount predicted over the known amount in absolute value so it would be |400-430/400| equaling to .075 which is 7.5% error
