         \rule{50}{1}\large\blue\textsf{\textbf{\underline{Question:-}}}\rule{50}{1}

            <em>Which of the following is equivalent to -9x>-27?</em>

<em />

<em>                                                       </em>\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}

\dagger First of all, we need to divide by -9 on both sides as follows:-

                                  \Large\bold{x < 3}

\dagger You may have noticed that the inequality sign changed from "greater than" to "less than".

     \bigstar This happened because we divided by a negative number on both sides.

<h3>Good luck with your studies.</h3>

-9x>-27

x<-27/-9

x<3

note: the sign of the inequality will change if the equation is divided/multiplied by a negative number

example : -x<-3 (×-1)

x>3

GREYUIT [131]

Answer:

  • Decay
  • Decrease rate is 8%

<u>The rate of decrease is </u>

  • 0.92 times

<u>Percent decrease is </u>

  • (1 - 0.92)*100% = 8%
