Answer:

x=6

Step-by-step explanation:

Given the x-intercepts of a parabola: x_1=3, x_2=9

The equation of symmetry at the parabola's vertex is x=h

Where h=\dfrac{x_1+x_2}{2}

In this case,

h=\dfrac{3+9}{2}=6

Therefore, the line of symmetry of the parabola is x=6 and is also the x-coordinate of the parabola's vertex.

The equation for line g can be written as y = x + 5. Parallel to line g is line h, which passes through the point (-6, -4). What
Irina18 [472]

Answer:

y=x+2

Step-by-step explanation:

we know the slopes have to be equal because the lines are parallel, so the slope is 1, or written as x. plug the point given, (-6,-4), and the slope, 1, into the y=mx+b equation to find the y-intercept. then solve. then put the slope and y-intercept together for the equation of line h.

y=mx+b, m=1, x=-6, y=-4

-4=(1)(-6)+b

-4=-6+b

2=b

y=x+2

Vaselesa [24]
I believe the answer is 1:5

If those numbers up top represent the number of cans of paint. This is because you must simplify to get the ratio, so 4:20 simplified would be 1:5 (Divide each side by 4)

Read the poem.

The Courage That My Mother Had  

by Edna St. Vincent Millay.

The courage that my mother had

Went with her, and is with her still:

Rock from New England quarried;

Now granite in a granite hill.

The golden brooch my mother wore

She left behind for me to wear;

I have no thing I treasure more:

Yet, it is something I could spare.

Oh, if instead she’d left to me

The thing she took into the grave!—

That courage like a rock, which she

Has no more need of, and I have.

In "The Courage That My Mother Had," what is the meaning of the line Now granite in a granite hill?  

The speaker wants to be more like her mother.

The speaker's mother has passed away.

The speaker's mother has turned to stone.

The speaker is visiting her mother's home.
