Answer:

= { \tt{(0, \: 0)}}

Step-by-step explanation:

Let:

{ \bf{ - x - 2y = 0 -  -  - (a)}} \\ { \bf{y =  - 8x -  -  - (b)}}

Substitute for y in equation (b) to equation (a):

{ \tt{ - x - 2( - 8x) = 0}} \\ { \tt{ - x + 16x = 0 }} \\ { \tt{x = 0}}

Also, y = 0

vodomira [7]

Answer:

The correct option is A,3875  passengers

Step-by-step explanation:

The curve of best fit for the date y=-5x^2+60x+3715

For April which month 4  which means that x is 4

By substituting 4 for x in the equation we can determine y, the number of passengers that arrived on flights at the airport  is determined thus.

y=-5*4^2+(60*4)+3715

y=-5*16+240+3715

y=-80+240+3715=3875

The number of passengers that arrived by flights in April, month 4 is 3875
