X+y+5=0
y=-x-5
If a solution exists y=y so we can say
x^2-9x+10=-x-5 add x+5 to both sides
x^2-8x+15=0 now factor
x^2-3x-5x+15=0
x(x-3)-5(x-3)
(x-5)(x-3) so x=3 and 5, using y=-x-5
y(3)=-8 and y(5)=-10
So the two solutions are:
(3,-8) and (5,-10)
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.
