-4>4(2-w)>-12

-1>2-w>-3

-3>-w>-5

3<w<5

~~~~~~~~~~~~~~~~~~~~~~~~~

If you're wondering why the sign changes when we divided (or multiplied) by a negative value, let's give a simpler example:

-5<-2 -> -5 is less than -2. That  expression makes sense. Now multiply that by -1. You get 5<x<2. Does that make sense? No. When you switch the signs of everything, the sign will always get switched.

Find the x and y intercept for -2x-5y=30
Ahat [919]

Answer:

see below

Step-by-step explanation:

-2x-5y=30

To find the x intercept, set y =0 and solve for x

-2x-5*0=30

-2x = 30

Divide each side by -2

-2x/-2 = 30/-2

x =-15

To find the y intercept, set x =0 and solve for y

-2*0-5y=30

-5y = 30

Divide each side by -5

-5y/-5 = 30/-5

y = -6
