First, let's multiply everything

-4 + 8x > 8

Add 4 to both sides

8x > 12

Divide by 8

x > 12/8

Simplify

x > 3/2

UNO [17]

Answer:

$y=\frac{3}{2} x-2$

Step-by-step explanation:

To find your slope using two points, use the slope formula.

$\frac{y2-y1}{x2-x1}$

Your y1 term is -5, your y2 term is 4.

Your x1 term is -2, your x2 term is 4.

$\frac{4-(-5)}{4-(-2)} \\\\\frac{9}{6} \\\\\frac{3}{2}$

Now that we have your slope, you can use the slope and one of your points in point-slope form to find your y-intercept.

$y-y1=m(x-x1)\\y-4=\frac{3}{2} (x-4)\\y-4=\frac{3}{2} x-6\\y=\frac{3}{2} x-2$

Answer:

perimeter = 4 $\sqrt{26}$

Step-by-step explanation:

Using the distance formula

AB = $\sqrt{(-4 - 1)^{2} + (3 - 4)^{2} }$

= $\sqrt{(-5)^{2} + (-1)^{2} }$

= $\sqrt{25 + 1}$

= $\sqrt{26}$

The perimeter of a square is 4 times the length of one side.

So, perimeter = 4 $\sqrt{26}$
