Answer: integer
Step-by-step explanation:
Step-by-step explanation:
So, √69 is between 8 and 9 . Since 69 is much closer to 64 than to 81 , the best whole number estimate is 8
Just draw x where the number gies
Answer:
X+(-49)=X/4
Step-by-step explanation:
A number represented by X
plus negative forty-nine
is equal to the number (X) divided by 4
-3x^2 + 12x -6
a = -3
b = 12
We calculate the vertex "x" value with this formula:
(vertex "x value") = -b / (2*a)
(vertex "x value") = -12 / -6
The vertex "x" value equals the axis of symmetry value.
The axis of symmetry is at x = 2.
