Sophia and London were Worked at a dry cleaners ironing shirts. Sophia Ken iron 40 shirts per hour, and London can iron 25 shirts per hour .Sophia and London worked a combined 11 hours and ironed 365 shirts shirts. write a system of equations that could be used to determine the number of hours Sophia and London worked and the number of London worked. You find the very abilities that you use to write the system.

it would be 6xy and -16xy.

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8

step-by-step explanation:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
