Whats the Axis of Symmetry? willing to give 15 points !!

nydimaria [60]

The axis of symmetry of a parabola in the form

$y=ax^2+bx+c$

is a vertical line

$x=k$

where k is the x coordinate of the vertex of the parabola.

The x coordinate of the vertex of the parabola is given by

$-\dfrac{b}{2a}$

which in your case is

$-\dfrac{-6}{2\cdot \frac{1}{4}}=\dfrac{6}{\frac{1}{2}}=6\cdot 2=12$

So, the axis of symmetry is the line x=12.

Gianni added 1 3/4 cup of pecans and 1 1/3 cup of walnuts to a recipe. How many cups of nuts did Gianni add to the recipe? I NEE

C - 3 1/12

Get a common denominator

3*3 / 4*3 + 1*4 / 3*4

Simplifies into 9/12 + 4/12

Adds to 13/12.

12 goes into 13 1 time, leaving us with 1 1/12

Add the 1 to the 2 full cups that already existed in the original problem - 3 1/12

Answer:

(-2, 4.111)

(-1, 4.333...)

(0,5)

(1, 7)

Step-by-step explanation:

So for this, you just substitute x with a cero to obtain the x-axis.

So, (0,5)

Then, you do the same with other numbers (replace x) and get the points to later graph it.

Also, you can use desmos, it really helps
