In the system of equations below, a and b are constants. For which of the following values of a and b does the system of equations have exactly two
real solutions?
y = 3
y = ax2 + b
O a = -2, b = 4
O a = 4, b = 3
O a = -2, b = 2
O a = 2, b = 4

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
