20,000 Hz = 2 × 10^4 Hz
150,000 Hz = 1.5 × 10^5 Hz
Please see the pic, I'd solved your question in it.
15x12=180
180$ simple unless u have a different way to do it
Answer:
(3,7) and (-3,-5)
Step-by-step explanation:
To solve the system of equations, graph both functions. The (x,y) point(s) where the functions intersect is the solution(s).
See attached picture.
Answer:
x < 3 or x > 9
Step-by-step explanation:
given 6| x - 6 | + 7 > 25 ( subtract 7 from both sides )
6| x - 6 | > 18 ( divide both sides by 6 )
| x - 6 | > 3
Inequalities of the form | x | > a always have solutions of the form
x < - a OR x > a, hence
x - 6 < - 3 or x - 6 > 3 ( add 6 to both sides in both inequalities )
x < 3 or x > 9
