For this case we must find the solution of the following quadratic equation:
Where:
Then, the solution is given by:
Substituting the values:
By definition we have:
Thus, we have two complex roots.
Answer:
The equation has no real roots.
Answer:
-4
Step-by-step explanation:
The slope of a line given two points is given by
m = (y2-y1)/(x2-x1)
= (-4-8)/(2 - -1)
= (-4-8)/(2+1)
= -12/3
= -4
18.5 hours
To solve this problem, you first need to figure out the average amount of money per hour the worker earns.
That would be the base salary plus the average tips per hour. So
$6 + $12 = $18
Then to figure out how many hours the worker needs to work, divide the goal by the hourly earnings. So
$333 / $18 = 18.5 hours.
Therefore on average, it will take 18.5 hours to earn $333, assuming a
base salary of $6/hour and an average of $12 in tips per hour.
Cost of 192 tile at $0.80 = 192 x .80 = $153.60
Change due from $200.00 =$200 - $153.60= $46.40
