Answer:

-6 7/hr= -6F per hour

Step-by-step explanation:

a rate of change can be defined as:

R=(total change in some quantity) (time in which the change happened)

In this case we know that the temperature dropped -30F in a given time, then we already know that:

Total change in some quanity =-30F now we know that this change took place between the 1:00pm and the 7:00 pm the total amount of ime between these two hours is:

T= (7.00 - 1.00 hr)= 6.00 hr

this means that the change happened =6 hours.

then we can replace these values in the above equation to get:

R=(-30F)/(6hr)=-6F/hr

this means that for each hours that passes the temperature decreases 6F

we also can write that this rate as:

R=-6F/HR =-6F per hour.

dybincka [34]

If your solving for x, you need to isolate/get the variable "x" by itself in the inequality:

-24 ≤ 3x - 9        First add 9 on both sides

-24 + 9 ≤ 3x - 9 + 9

-15 ≤ 3x        Then divide 3 on both sides to get "x" by itself

\frac{-15}{3} \leq \frac{3x}{3}

-5 ≤ x                  [or  x ≥ -5 if you prefer "x" to be on the left side]
