1.) Factor 9u^2-12u
2.) Cancel any common factors (in bold will be the terms eliminated)
Final answer is:
3u-4
Therefore, the answer is
C. 3u-4
Frequency (f) in Hz = Wave speed (c) in m/s/Wavelength in m
Wave speed = 60 m/s, Wavelength = 1.2 m
Therefore,
f= 60/1.2 = 50 Hz
Answer:
4 Containers needed to Fill 3 Two lbs Bags Of Candy .
Step-by-step explanation:
According to Question, We have
2 lbs Bag Of Candy Used To Fill Container That hold lbs Each .
Now There are 4 Container of Capacity lbs Needed To fill Exactly 3 two lbs Bags .
Thus 4 containers have Total capacity Of 6 lbs . Which Is Easily Filled By The 3 two lbs Bags . ( Without Any Loss )
Y = -1/2x + 4
X + 2y = -8
Replace y in the second equation with the first one:
X + 2(-1/2x +4)=-8
Simplify:
X -X +8 = -8
Simplify:
8 = -8
Subtract 8 from both sides:
0 = -16
This is a false statement, so there are no solutions.
