Answer:
7.8 × 10-5 meters
Step-by-step explanation:
the length of the a human hair= 8.4 x 10^-5
length of the vicuna hair:0.000006 = 0.6 x 10^-5
===========================================
difference between human hair and vicuna hair:
8.4 x 10^-5 - 0.6 x 10^-5 = 10^-5 ( 8.4 - 0.6)
= 10^-5 (7.8)
= 7.8 x 10 ^-5 meters
21≥<span>3(a-7) +9
first, just solve it like a normal equation
Distribute
21</span>≥3a-21+9
<span>Combine numbers
21</span>≥3a-12
<span>Solve like equation
33</span>≥3a
11≥a
<span>"a" has to be less than or equal to 11 for the inequality to be true

I can’t do it without the graph :(
