Sketch the graph of y = (x + 3)2 – 4 and identify the axis of symmetry.
Sloan [31]

Answer: Thought I’d return the favor and help u with this question! But anyways, the axis of symmetry is at x = -3.

Explanatio: This can be found by looking at the basic form of vertex form:

y = (x - h)^2 + k

In this basic form the vertex is (h, k). By looking at what is plugged into the equation, it is clear that h = -3 and k = -4. This means the vertex is at (-3, -4).

It is a fact that the axis of symmetry is a vertical line of x = (vertex value of x). So we can determine that the axis of symmetry is at x = -3

i hope this helps u

You are redecorating your bedroom and want to place two posters on the wall. Your wall is 11 feet, 6 inches long and each poster
lidiya [134]
Mark Brainliest please

Answer: not reasonable

Explanation

Let 'x' represent the distance between the posters and the distance from the posters to the nearest edge of the wall.

1 ft = 12 in

11 ft = 11*12 in

14 ft = 132 in

Now we can write the following equation:

6x + 2*36 = 132 + 3
6x + 72 = 135

X = 10.5 in

he poster should be placed 10.5 inches from the edge of the wall.

Your brother is not reasonable .
