Answer:
A. 9y - x = 2
Step-by-step explanation:
9y - x = 2. First to get x on the other side we add x to both sides gettings us this. 9y -x + x = 2 + x or just 9y = x + 2. Then divide by 9 to get y alone. We then get y = x/9 + 2/9. The rate of change is clearly not y = 9x here, it's y = x/9 or 1/9x.
Answer:
63.5 feet/minute
Step-by-step explanation:
She first descended 1,024 feet in 17 minutes
Then she descended 500 feet in 7 minutes
The total feet descended is 1,024 + 500 = 1,524 feet
The total time to descend is 17 + 7 = 24 minutes
The average rate of change in altitude is
Altitude descended / time
1,524 feet / 24 minutes
63.5 feet /minute
Answer:
x = 22
Step-by-step explanation:
90 = (5x - 20)
+20 +20
110 = 5x
/5 /5
22 = x
Hope this helps!
