Answer: H =
Step-by-step explanation:
Step 1: Add h to both sides.
hx+x²+h=−h+x+h
hx+x²+h=x
Step 2: Add -x^2 to both sides.
hx+x²+h+−x²=x+−x²
hx+h=−x²+x
Step 3: Factor out variable h.
h(x+1)=−x²+x
Step 4: Divide both sides by x+1

<u>Answer:</u>
The temperature change per hour was -3 degrees per hour.
<u>Step-by-step explanation:</u>
We know that the temperature fell from degrees to
degrees in a time period of
hours.
So to find the rate of change of the temperature, we will divide the change in temperature by the number of hours.
For that, we will change the mixed number into improper fractions and then solve:
Temperature change per hour =
Therefore, the temperature change per hour was -3 degrees per hour.
