How do you solve and graph -82 is less than or equal to 9x OR -1 is less than or equal to -28

vovikov84 [41]

Since $-1\nleq-28$ , you can eliminate this part.

So you're left with
$-82\leq9x$
⇒ $9x\geq-82$
⇒ $x\geq-\frac{82}{9}$

which is about -9.11111...

You do not need to flip the inequality sign when solving the inequality -3 t + 7 ≥ 9.

NemiM [27]

For this case we must resolve the following inequality:

$-3t + 7 \geq9$

Subtracting 7 from both sides of the inequality we have:

$-3t \geq9-7\\-3t \geq2$

Dividing by 3 to both sides of the inequality we have:

$-t \geq \frac {2} {3}$

We multiply by -1 on both sides, taking into account that the sense of inequality changes:

$t \leq- \frac {2} {3}$

Thus, it is observed that to solve the inequality it is necessary to change the meaning of it.

ANswer:

False. It is necessary to change the sense of inequality
