Question

Need help with question 3. Part D the four parts in part D I need answered please.

Answer 1

The given inequality is:

`2x+4<-x+1`

Simplifying it:

`\begin{gathered} 2x+x<1-4 \\ 3x<-3 \\ x<-1 \end{gathered}`

So:

a) English - All real number less than equal to -1.

b). Algebraic - x<-1

c). Number line: i used open circle on number line at -1 because x is not equal to -1 so it should not be included.

d). Interval notation:

`(\infty,-1)`
