Last one:
2 x + 4 y = 6. 3 x minus 4 y = 9.
Step-by-step explanation:
2x + 4y = 6
3x - 4y = 9
4y = 3x - 9
2x + 3x - 9 = 6
5x = 15
x = 3
4y = 3(3) - 9
4y = 0
y = 0
Only one solution, which is (3,0)
Answer:
2x+4y =6
3x -4y =9 one solution
Step-by-step explanation:
4x+2y =8
-4x-2y =3
Adding these together
0 =11 False no solutions
-5x +y =6
5x -y = -6
Adding these together
0 = 0 True we get Infinite solutions
-3x+4y =2
3x-4y =0
Adding these together
0=2 False no solutions
2x+4y =6
3x -4y =9
Add these together
5x =15
Divide by 5
5x/5 = 15/5
x =3
2(3) +4y =6
10 +4y =6
4y = 0
y = 0
(3,0)
One solution

Answer:
y=0.75x+5
Step-by-step explanation:
It would be this equation because you start at 5, which is the y-intercept, then you add 0.75 for every pound of apples. So on a graph you would start at 5 on the y-line then go up by 0.75
