Answer:

Vertex: (-4, 1)

X intercepts: (-6, 0) and (-2, 0)

Y Intercepts: (0, -5)

Axis of Symmetry: X= -4

Step-by-step explanation:

Vertex of the parabola is the maximum or minimum point on the graph of the quadratic function

X intercepts are points of when a line or in this case a parabola intercepts the x axis, and where y = 0

Y intercepts are point of when a line or in this case a parabola intercepts the y axis, and where y = 0

Axis of symmetry is the point where if you divide the parabola in half, shows a symmetrical side

Describe a way to make the arithmetic problem 45% x 680 mentally
lord [1]

Answer:

306.

Step-by-step explanation:

Firstly, we are aware 100% of 680 is obviously 680,

Next, we know half of a 100% is 50% therefore half of 680 is 340.

Then, we know 45% is 5% less than 50%

To find 5% of a number mentally, divide it by 10 as 100÷5=20

680÷20=34

Lastly 50% subtracted by 5%: 340-34=306.

Now we know, 45% of 680 is 306.
