Question

Which systems of equations has a solution of approximately (-2.7,-1.2)

Answer 1

The appropriate choice is ...
  1) 4x-5y=-5 and 3x+10y=-20

Answer 2

Answer:

option A

Step-by-step explanation:

systems of equations has a solution of approximately (-2.7,-1.2)

To find system of equations , we plug in the given point  for x  and y in each option and check which two equations satisfies our given point

$4x-5y=-5\ and \ x+10y=-20$

$4x - 5y =-5$

Plug in the given point

$4(-2.7) - 5(-1.2) =-5$

-4.8 = -5

We are given with approximate solution, -4.8 is close to -5. So it satisfies our given solution

$3x+10y = -20$

$3(-2.7)+10(-1.2) = -20$

20.1= 20

It is approximately same

$4x - 5y =-5$ and $3x+10y = -20$ satisfies the given solution
