Answer:
x = 8, -4
Step-by-step explanation:
2x-4-6=6; therefore, x = 8
2x-4=-12; therefore, x = -4

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:
Because each of the two numbers is a factor of the product, and since the
product has at least those two factors, it's a composite number by definition.

Answer:
( x )² + ( y - 3 )² = 16
Step-by-step explanation:
The general format for circular equations is ( x - a )² + ( y - b )² = r²
