What are the coordinates of the vertex of the parabola y=x^2+2x-1

1 answer:

3 0

Y = x^2 + 2x - 1 = x^2 + 2x + 1 - 1 - 1 = (x + 1)^2 - 2
The vertex of a parabola given by y = a(x - h)^2 + k is (h, k).

Therefore, the vertex of y = (x + 1)^2 - 2 is (-1, -2)

How do I write an inequality for 6x+8>2

Hatshy [7]

Answer:

The inequality is $x>-1$

Step-by-step explanation:

Given:

The inequality to solve is given as:

$6x+8>2$

Now, in order to solve it for 'x', we need to isolate 'x' on one side of the inequality.

Adding -8 on both sides, we get:

$6x+8-8>2-8\\\\6x>-6$

Dividing both sides by 6, we get:

$\frac{6x}{6}>\frac{-6}{6}\\\\x>-1$

Therefore, the inequality for 'x' is given as:

$x>-1$

So, 'x' include all the values that are greater than -1.
