Answer:

18 < x

Step-by-step explanation:

15 < x - 3

Add three too both sides to get ride of the three on the right

Answer:

$y = {x}^{2} - 2$

Or if you want with the value of h too.

$y = {(x - 0)}^{2} - 2$

Step-by-step explanation:

$y = a {(x - h)}^{2} + k$

Find the value of h and k by using the formula.

$h = - \frac{b}{2a} \\ k = \frac{4ac - {b}^{2} }{4a}$

From y = x²-2

$a = 1 \\ b = 0 \\ c = - 2$

Substitute these values in the formula.

$h = - \frac{0}{2(1)} \\ h = 0$

Therefore, h = 0.

$k = \frac{4(1)( - 2) - {0}^{2} }{4(1)} \\ k = \frac{ - 8}{4} \\ k = - 2$

Therefore, k = - 2.

From the vertex form, the vertex is at (h, k) = (0,-2). Substitute h = 0, a = 1 and k = -2 in the equation.

$y = a {(x - h)}^{2} + k \\ y = 1 {(x - 0)}^{2} - 2 \\ y = {(x)}^{2} - 2 \\ y = {x}^{2} - 2$

These type of equation where b = 0 can also be both standard and vertex form.

Find the slope of the line passing through the points (-2,-7) and (3,5).

Oduvanchick [21]

Answer:

12/5

Step-by-step explanation:

m= slope

m=Y2-Y1/X2-X1

Y2=5, Y1=-7, X2=3, X1=-2

Substitute into equation

m=5-(-7)/3-(-2)

m=5+7/3+2

m=12/5

slope is 12/5
