\\ \sf\longmapsto \dfrac{x^2-1}{x^2+5x+4}\leqslant 0

  • Solving denominator

\\ \sf\longmapsto x^2+5x+4>0

\\ \sf\longmapsto x^2+4x+x+4>0

\\ \sf\longmapsto x(x+4)+1(x+4)>0

\\ \sf\longmapsto (x+4)(x+1)>0

\\ \sf\longmapsto x>-4\:or x>-1

  • Hence x\neq-1
  • x can't be 0 as it makes function undefined

\\ \sf\longmapsto -4

Which system of inequalities has a solution set that is a line?
Korolek [52]

We're going to solve each of the systems to determine the solution.

<u>System 1</u>

x+y \geq  3\\ x+y \leq  3

using a graph tool

the solution is the line x+y=3

see the attached figure N 1

<u>System 2</u>

x+y \geq  -3\\ x+y \leq  3

using a graph tool

the solution is the shaded area

see the attached figure N 2

<u>System 3</u>

x+y >  3\\ x+y <  3

using a graph tool

The system has no solution

see the attached figure N 3

<u>System 4</u>

x+y >  -3\\ x+y <  3

using a graph tool

the solution is the shaded area

see the attached figure N 4

therefore

<u>the answer is</u>

<u>System 1</u>

x+y \geq  3\\ x+y \leq  3
