Ответ:
B
Step-by-step explanation:
4 or greater: 1/2 (4,5,6)
4 or smaller: 2/3 (1,2,3,4)
1/2 * 2/3 = 2/6
2/6 = 1/3
1/3 = 0.333

Step-by-step explanation:
We have given two equations:
3x - y = 15
6x - 2y = 30
Consider A. (6,3)
Plug x= 6 and y = 3 in both the equations And see what we get:
3x - y = 15
or 3×6 - 3 = 15
or 18 - 3 = 15
or 15 = 15 ,
And
6x - 2y = 30
or 6×6 - 2×3 = 30
or 36 - 6 =30
or 30 = 30
so this point (6,3) is the solution of system of equation
Next, B. (7 , 6)
Again we do the same steps:
Plug x= 7 and y = 6 in both the equations
3x - y = 15
or 3×7 - 6 = 15
or 21 - 6 = 15
or 15 = 15
And
6x - 2y = 30
or 6×7 - 2×6 = 30
or 42 - 12 =30
or 30 = 30
The point (7,6) is the solution of system of equation
Next, C. (8,9)
Plug x=8 and y =9 in both the equations
3x - y = 15
or 3×8 - 9 = 15
or 24 - 9 = 15
or 15 = 15
And
6x - 2y = 30
or 6×8 - 2×9 = 30
or 48 - 18 =30
or 30 = 30
The point (8,9) is also the solution of system of equation
Hence all the points (6,3),(7,6) and (8,9) are the solution of given system of equations.
