Answer: $13.70
Step-by-step explanation:
.10* 17= 1.7, because $.10 is charged for everyday the book is late and the books were 17 days late.
1.7* 4= 6.8, because there were four books that were 17 days late.
.10* 23= 2.3, because $.10 is charged for everyday the book is late and the books were 23 days late.
2.3* 3= 6.9, because there were three books that were 23 days late.
6.8+6.9= 13.70 is the amount of money Sydney had to pay the library for her late books.
When:
a = b = 0 we have point (0,0).
a = 0 and b ≠ 0 vertical line segment from (0, -b) to (0, b)
a ≠ 0 and b = 0 horizontal line segment from (-a, 0) to (a, 0)
a ≠ 0 and b ≠ 0 a ≠ b ellipse
a ≠ 0 and b ≠ 0 a = b circle
41.00
25% off $45 is 33.75
You then add 7.25 to 33.75 which is $41
If a third plane could be drawn which contains both lines a and b, then lines a and b must be parallel. <span>if two lines do not intersect on the same plane, they are parallel. Furthermore, if a line is in a plane and another line is in a parallel plane, you cannot draw another plane </span><span>which contains both lines a and b, only if the lines are parallel.</span>
6x - y = 31 so y = 6x - 31
substitute y = 6x - 31 into 3x + 7y = 8
3x + 7y = 8
3x + 7(6x - 31) = 8
3x + 42x -217 = 8
45x = 225
x = 5
y = 6x - 31
y = 6(5) - 31
y = 30 - 31
y = -1
answer
x = 5 and y = -1
