-2|2.2x-3.3|=-6.6 solve for x
2 answers:
-2[2.2x-3.3]=-6.6
[2.2x-3.3]=-6.6 /-2
[2.2x-3.3]=3.3
We have two equations:
1)
2.2x-3.3=3.3
2.2x=3.3+3.3
2.2x=6.6
x=6.6/2.2
x=3
2)
2.2x-3.3=-3.3
2.2x=-3.3+3.3
2.2x=0
x=0/2.2
x=0
Answer: we have two solutions: x=0 and x=3.
-2|2.2x - 3.3| = -6.6. From it: |2.2x - 3.3| = 3.3. We have 2 variants: 1) 2.2x - 3.3 = -3.3. Then 2.2x = -3.3 + 3.3, so 2.2x = 0 => x = 0. 2) 2.2x - 3.3 = 3.3. Then 2.2x = 3.3 + 3.3, so 2.2x = 6.6 => x = 3. Answer: 0; 3.

Answer:
659.6 ft
Step-by-step explanation:
x = 140 / tan 23
x = 329.82(rounded to hundredth)
so total ground distance between the cables = 2x = 2(329.82) = 659.64 feet
60$. These are my equations :
600 * 0.2 = 120 ; 600 - 120 = 480
Then...
600 * 0.1 = 60 ; 600 - 60 = 540
Which then became....
540 - 480 = 60
