-2x+4y=-8 which graph models the equation

katovenus [111]

Hello!

First you have to get the equation into slope-intercept form

Slope-intercept form is y = mx + b

-2x + 4y = -8

Add 2x to both sides

4y = 2x - 8

Divide both sides by 4

y = 1/2 x - 2

The graph is a line that goes through the points (0, -2), (-2, -3), (2, -1) and
(4, 0)

Hope this helps!

Two step inequalities 5x-7_>8

Naddik [55]

Answer:

x ≥ 3

Step-by-step explanation:

5x - 7 ≥ 8

5x ≥ 8 + 7 (You take the common terms to one side)

5x ≥ 15

$\frac{5x}{5} \geq \frac{15}{5}$

x ≥ $\frac{15}{5}$

x ≥ 3

PLEASE ANSWER! Given the functions f(x) = x2 + 6x - 1, g(x) = -x2 + 2, and h(x) = 2x2 - 4x + 3, rank them from least to greatest

Ratling [72]

Answer:

<em>he rank from least to great based on their axis of symmetry: </em>

0, 1, -3 ⇒ g(x), h(x), f(x)

So, <em>option C</em> is correct.

Step-by-step explanation:

A quadratic equation is given by:

$ax^2+bx+c =0$

Here, a, b and c are termed as coefficients and x being the variable.

<em>Axis of symmetry can be obtained using the formula</em>

$x = \frac{-b}{2a}$

Identification of a, b and c in f(x), g(x) and h(x) can be obtained as follows:

$f(x) = x^2 + 6x - 1$

⇒ a = 1, b = 6 and c = -1

$g(x) = -x^2 + 2$

⇒ a = -1, b = 0 and c = 2

$h(x) = 2^2 - 4x + 3$

⇒ a = 2, b = -4 and c = 3

So, axis of symmetry in $f(x) = x^2 + 6x - 1$ will be:

$x = \frac{-b}{2a}$

x = -6/2(1) = -3

and axis of symmetry in $g(x) = -x^2 + 2$ will be:

$x = \frac{-b}{2a}$

x = -(0)/2(-1) = 0

and axis of symmetry in $h(x) = 2^2 - 4x + 3$ will be:

$x = \frac{-b}{2a}$

x = -(-4)/2(2) = 1

<em>So, the rank from least to great based on their axis of symmetry: </em>

0, 1, -3 ⇒ g(x), h(x), f(x)

So, <em>option C</em> is correct.
