Answer:
A crest is the highest point of a wave.
A trough is the lowest point of a wave.
Infrasound is sound below the limit that humans can hear, below 20 Hz.
Ultrasound is sound above the limit that humans can hear, above 20,000 Hz.
We know the slope formula
Parallel lines have equal slope so it has m=-2
0.29m+10=0.35m
0.29m-0.29m+10= 0.35m-0.29m
10=0.06 m
Divide by 0.06 for 10 and 0.06
10/0.06= 0.06/0.06 m
m= 166.66666
Answer is m = 166.66666- the number 6 continues
From order of operations, we do multiply/divide first, then add/subtract. So:
(I assume that is 8 times 2, and 5 times x, solving for x)
6+8<span>⋅</span>2 = 5x
6 + 16 = 5x
22 = 5x
x = 22/5 (twenty two fifths)
