Answer: x = - 3

Step-by-step explanation:

The equation is in a standard form of equation as;

y = ax^2 + bx + c, and therefore, the axis of symmetry is given by the formula,

X = - b / 2a.

Therefore using that in the question, a = 1 and b= 6

Therefore, the axis of symmetry is:

x = - (6) / 2(1) which gives

x = - 3

How does a digit in the 10,000s place compare to a digit in the thousands place?

Delvig [45]

While a digit in the thousands place has a value 1,000 times the value of the digit. So to compare you can do 10,000 / 1,000 = 10, which means that a digit in the ten thousand place values ten times what the same digit values is it is the thousand place.
