Answer:
Step-by-step explanation:
Let the two numbers be x and y
So we have:
using the elimination method, add the two equations together:
solve for x:
substitute our value for x back into the first equation we made:
therefore,
Answer:
2.3
Step-by-step explanation: if your finding the decimal 2.3 will be your answer if not then sorry
Answer:
8.0 seconds to the nearest tenth,
Step-by-step explanation:
h=-16t^2 +vt + c.
-16t^2 + 116t + 101 = 0
t = [ -116 + /- √(116^2 - 4*-16*101) ] / (-32)
t = (-116 +/- √19920) / (-32)
t = -0.79, 8.036 (we ignore the negative root)
The time in flight = 8.036 seconds.
Using inequality for the give interval which states that :
A function lies in an open interval from -2 to 6.
Hence,we can rewrite it as :
-2 < x < 6
