The value of h is exactly the axis of symmetry. So when h changes, it completely changes the line of symmetry. This is because the vertex is (h, k) and the x value of the vertex is always equal to the line of symmetry in a quadratic.
Changing the k value does nothing to the line of symmetry. This is because it is just moving the graph up and down, which doesn't change the symmetry of a parabola.

Answer: C. x+y = 4</h3>
This is the line through points A and C, which is one of the diagonals. Reflecting any square over its diagonal will result in the same figure. We can say it's symmetrical about the diagonal line.
Put another way, reflecting point B over the line x+y = 4 will have it land on point D. Then point D will move to where B used to reside. In short, points B and D swap places. Points A and C will stay fixed in place.
10/2+1/2 - 12/6+1/6. -> change the 5 and 6 to fractions
= 11/2 - 13/6. -> add up
= 33/6 -13/6. -> multiply the first fraction by 3 so.
that you have the same denominators
= 20/6. -> subtract
= 10/3
= 9/3 +1/3
= 3 1/3
Answer: c
Step-by-step explanation:
3x1,789=5367. as for y 3 digit number is like multiplying a 4 digit number, it's basically the same thing just one digit more.
