The graph of a quadratic function is a parabola.
 The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola. The x coordinate of the vertex is the equation of the axis of symmetry of the parabola.
 Taking into account the definition above, then the other intersection with x will be:
 horizontal distance between the axis of symmetry and intersection with x:
 d = 7 - (- 1) = 7 + 1 = 8
 The second intersection will then be:
 x2 = -1-8 = -9

 Answer: 
 the other x-intercept is:
 x2 = -9

givi [52]

Answer:

Kami will need 33.6 ounces of ground beef for the recipe

Step-by-step explanation:

From the problem, we know that one person will use up 1.6 ounces of ground beef. We also know that there are 21 people that will be attending the party. Each of those 21 people will definitely use up 1.6 ounces of ground beef.

Hence, for the recipe to be perfect, Kami will have to use 21 X 1.6 ounces  = 33.6 ounces of ground to make the recipe for the entire dinner.

enyata [817]

The cinnamon-scented jar candle brunt faster.

<h3>What does relative speed means ?</h3>

Relativity means observing some action with different perspective.

Suppose you are moving in a bus at 100 km/hr and you are reading a book.To an observer which you are passing by you and the book he observes moving at a speed of 100 km/hr.But for you the book is not moving at all because both you and the book is moving at a speed of 100 km per hour.

According to the given question Andrei had cinnamon-scented jar candle that burned for 303030 hours and a berry-scented pillar candle that burned for 888888 hours.

From the given data of burning hours we can observe that berry-scented pillar candle that burned for 888888 hours which is more that of Andrei had cinnamon-scented jar candle that brunt for 303030 hours because

30303030 < 888888.
