Multiple Choice

Find the values of x that will satisfy

 $\frac{(𝑥+1)}{(𝑥−4)}≥0$  

•  $\left(-\infty,-4\right)U\ \left[1,+\infty\right)$  

•  $\left(-\infty,-4\right]U\ \left[1,+\infty\right)$  

•  $\left(-1,-4\right)U\ \left[1,4\right]$  

• set of real number

Multiple Choice

TRUE OR FALSE:

When solving rational inequality, we need to move all the terms in one side, combine like terms and write as a single fraction

• TRUE

• FALSE

Multiple Choice
