Answer: (-2/3 , 3) is the answer
Answer: The answer is NO.
Step-by-step explanation: The given statement is -
If the graph of two equations are coincident lines, then that system of equations will have no solution.
We are to check whether the above statement is correct or not.
Any two equations having graphs as coincident lines are of the form -

If we take d = 1, then both the equations will be same.
Now, subtracting the second equation from first, we have

Again, we will get the first equation, which is linear in two unknown variables. So, the system will have infinite number of solutions, which consists of the points lying on the line.
For example, see the attached figure, the graphs of following two equations is drawn and they are coincident. Also, the result is again the same straight line which has infinite number of points on it. These points makes the solution for the following system.

Thus, the given statement is not correct.
Well first-
Mason planted 12 bushes in one hour, so basically all you have to do is multiply the amount of bushes planted in a hour (12) by the hours (3) so-
12 x 3 = 36 plants for 3 hours

Think of x(symbol)y as a function like f(x)=3x-y. Since the first symbol we see is in parenthesis, we know that x=-1 and y=-2. Plug that into f(x), and you get 3(-1)-(-2)=-1. So know we have the x value for the second symbol, which is -1, and the y value, which is seen to the right: (-3). Plug that back into f(x), and you get 3(-1)-(-3)= 0. Your answer should be A: 0.
