the answer is (x )
math way helps
Step-by-step explanation:
The one missing is the fourth choice.
As you can see, the x axis stands for the weight, and the y axis the total cost.
You can see that the point, (1, 4) definitely exists.
So basically it would be 1 pound of cheese for four dollars, since x is weight and y is total cost.
You can see the fourth choice states that it's four dollars for one pound of cheese.
Hope this helped :)
Answer:
(-4,1)
Step-by-step explanation:
The answer is (-4,1) because if you reflect any point on the y axis, the y will stay the same, but the x will become the opposite. The opposite of 4 is -4, so the coordinates are (-4,1).
The coefficient matrix is
Its determinant is then
which is equal to 0.
