Answer:
Except k=7, any real number for k would cause the system of equations to have no solution.
Step-by-step explanation:
In general a system of equations can be represented as ax+by=c and dx+ey=f. In order this system of equations to have NO SOLUTIONS a/d=b/a≠c/f. In our example a=6, b=4, c=14, d=3, e=2 and f=k. To apply the formula above, 6/3=4/2≠14/k. Hence k≠7. It can be concluded that except k=7, any real number for k would cause the system of equations to have no solutions.
Just for information, if k=7 the system will have infinitely many solutions.
Answer:
d
Step-by-step explanation:
They are equal
5x-2x+18=3(x+6) Distribute the right side
5x-2x+18=3x+18 Subtract 18 from both sides
5x-2x=3x Add 2x to both sides
5x=5x And you would find out that both sides are equal

You can use them to help understand quantities such as
x, y
1, 2
2, 4
3, 6
this helps to show relation such as adding by two or you can have a multiplying rate of change whi chub can show that each time a number is multiplied by something it changes
like if the question states: Bob puts $500 into the bank and he collects interest of $10 once a week how much money does he make in interest in 4 weeks.
x, y
0, 500
1, 550
2, 600
4, 650
