7 times 4 =28 this is cuz there is seven days in a week and 7x4
We know that this is a parabola, as the equation is denoted by the x^2 term.
We can see that the symmetry is seen at the point -0.5, therefore making the axis of symmetry the vertical line -0.5.
The vertex is found in quadrant three. In other words, it will shift by a negative value both horizontally and vertically. The vertex is therefore (-0.5, -0.5).
We can verify this in the equations by using the formula (-b/2a) to find the vertex. The only quadratic equation that satisfies this is -2x^2 + 2x -1.
To sum it up, the answers are:
-2x^2 + 2x - 1.
AoS: x = -0.5
Vertex: (-0.5, -0.5).
Answer:
Step-by-step explanation:
n/3 - 2 = 4 Add 2 to both sides
n/3 - 2 + 2 = 4+2 Combine
n/3 = 6 Multiply both sides by 3
3*n/3 = 6 * 3
n = 18
It’s the second one, (10,-9)
