What is the solution to StartFraction h over negative 24 EndFraction less-than-or-equal-to 18?

attashe74 [19]

Answer:

h greater-than-or-equal-to negative 432

Step-by-step explanation:

$\frac{h}{-24} \leq 18$

* multiply each side by -24 *

$\frac{h}{-24} *-24=h\\-24*18=-432$

IMPORTANT NOTE: when multiplying an inequality by a negative number you must flip the sign. So if the inequality sign was once facing the constant ( 18 ) then it will flip and face the variable ( h )

Thus,

h ≥-432

Which can also be expressed as h is greater than or equal to negative 432

Extra notes: You only have to flip the inequality sign if it's being multiplied by a negative number. Meaning if its multiplied by a positive number then the inequality sign does not flip.

If we were to take a look at the problem we would see that the greatest difference would be the greatest difference from 0, either positive of negative;

Student A: 1 from 0,

Student B: 0 from 0,

Student C: 3 from 0,

Student D: 2 from 0

As we see from the results, Student C has the greatest difference from before
