Exercise 6 Page 55

Substitute -6 into the given inequality and then simplify.

No

Practice makes perfect
We can determine whether -6 is a solution by substituting it into the inequality and simplifying using the order of operations.
4x-25>-2
4({\color{#0000FF}{\text{-} 6}}) - 25 \stackrel{?}> \text{-} 2
\text{-}24-25\stackrel{?}> \text{-} 2
- 49≯- 2
Since -49 is less tan -2, -6 is not a solution to the inequality.
