Question

Solve.



–4t ≤ 48



A.t ≥ –12


B.t ≤ –12


C.t ≥ 12


D.t ≤ 12

Answer 1

Do you know how to work with inequalities? Such as when you divide them?

Answer 2

No ma'am

Answer 3

In this case we have -4t greater than or equal to 48.

Answer 4

We would divide by -4 to both sides, but since we are dividing by a negative, we must flip the inequality sign.

Answer 5

what is 48/-4?

Answer 6

We will start with that.

Answer 7

ok

Answer 8

48/-4=-12. Becuse -12 x -4 = 48. Correct?

Answer 9

–4t ≤ 48
/-4 /-4
t≤-12
but we must flip the sign because we divided by a negative.
A seems to be your answer.



A.t ≥ –12


B.t ≤ –12


C.t ≥ 12


D.t ≤ 12

Answer 10

Hopefully, that makes sense. I am pretty positive it is when you both divide AND multiply by a negative, that sign MUST be flipped. if 4 was positive, the sign would not need flipped, because it is greater than 0.

Answer 11

oh ok thx

Answer 12

You're welcome.

Answer 13

wait

Answer 14

how u get 48

Answer 15

In your original equation we have -4t≤48.
That is just from the original equation. However, t need to be alone, so then we dividde by -4.

Answer 16

oh ok ok

Answer 17

I hope that makes sense :-) Remember your signs when you divide/multiply by a number that is less than 0. Flip them.

Answer 18

ok ill remember

Answer 19

Perfect. If you need any extra help, mention me, I will help.
