Here we go ~
The air plane descends 15 feels every 1.45 seconds, so it's unit rate is :

Now we have to calculate the descent in 3.5 minutes ~


So, the airplane descends 2172.41 feels in three and a half minutes ~
Answer:
106
Step-by-step explanation:
When the decimal is 5 or greater, we round up. When the decimal is less than 5, we round down. For example, 105.4 would be rounded down to 105 because 4<5

Answer:
x = -8
Y = -11
Step-by-step explanation:
Given
Y = 3x + 13
Y = x - 3
Substitute x - 3 for Y in the first equation
We have
Y = 3x + 13
x - 3 = 3x + 13
Add 3 to both sides
x - 3 + 3 = 3x + 13 + 3
x = 3x + 16
Subtract 3x from both sides
x - 3x = 3x - 3x + 16
-2x = 16
Divide both sides by -2
x = 16/-2
x = -8
Now substitute -8 for x in any of the above equations to get Y.
Using the second equation, we have
Y = x - 3
Y = -8 - 3
Y = -11
