Step-by-step explanation:
Step-by-step explanation:
Since <em>a</em> is the final altitude after <em>t</em> minutes, we can plug in 21,000 for <em>a</em> in the given equation.
21,000 = 3400t + 600
Solve for t.
20,400 = 3400t
t = 6 minutes
By just changing the x and numbers you can solve it:
-4x=-8 => x=2
