If you distribute a negative factor, should you flip the inequality symbol? And why be specific
Alchen [17]
You flip is when you mulitply the whole equation by a negative
not when you distribute a  negative
if yo had
-3(x+4)>x
you wouldn't flip the negative symbol when distributing then -3

but if you had
-3(x+4)>-x
you would eventually have to multiply by -1 to make +1x

 
because they will be differente
exaple

12>3 is true
if yo multiply negative
-12>-3 is fale
-12<-3 is true

anothe rexample with placeholders
x<x+2
mulitply -1
-x>-x-2
false
-x<-x-2
true
that is why we flop the inequality symbole

The graph of the solution to this inequality is: C. number line with an open circle plotted at negative eight and arrow pointing left.

<h3>What is a number line?</h3>

A number line simply refers to a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.

Next, we would solve the given inequality as follows:

−0.4b + 2.4 < 5.6

Subtracting 2.4 from both sides, we have:

−0.4b + 2.4 - 2.4 < 5.6 - 2.4

−0.4b < 5.6 - 2.4

−0.4b < 3.2

Dividing both sides by -0.4, we have:

b < -3.2/0.4

b < -8

In conclusion, the circle on a number line should be open and would point to the left when the inequality symbol is <.
