Answer:
after 7 minutes
19,600 feet
Step-by-step explanation:
Here's the "pencil and paper" solution:
The two altitude equations are ...
y = 41300 -3100x
y = 2800x
They can be solved by setting the expressions for y equal to each other.
2800x = 41300 -3100x
5900x = 41300
x = 41300/5900 = 7
y = 2800·7 = 19600
The planes will both be at 19,600 feet after 7 minutes.
Answer:
x^2-16
Step-by-step explanation:
A= (b)(h)
A= (x+4)(x-4)
x^2-4^2
x^2-16

Answer:
15° C.
Step-by-step explanation:
To do this, we will need to plug in and solve.
59 = 9/5c + 32
Isolate the variable by subtracting 32 by both sides:
27 = 9/5c.
Divide both sides by 9/5, giving you:
15° C.
