8 - 5x <-2

8 (-8) - 5x < -2 (-8)

-5x < -10

-5x/-5 < -10/-5

x > 2 (flip the sign because you divided by a negative number

x = 3, 4, 5

your answer is 3, 4, 5

note that it isn't 2, because it isn't a ≥, which means that it cannot be 2

hope this helps

A(-5,-4) ——> A’ is a glide reflection where the translation is (x,y)—->(x+6,y), and the line of reflection is y=3. What ar

Nastasia [14]

Solution:

The Point in the coordinate plane is A(-5,-4).

Perpendicular or shortest Distance from line y=3 that is (-5,3) to point (-5,-4) is

$=\sqrt{(-5+5)^2+(3+4)^2}\\\\=7$

When it is reflected through the line, y=3, the coordinate of point A (-5,-4) changes to (-5,3+7)= B(-5,10).

Now, the Point B is translated by the rule , (x,y)—->(x+6,y),

So,the point B is translated to, (-5+6,10)=(1,10)

Option C: (1,10) is the glide reflection of point A(-5,-4).
