The solution to the given inequality as represented in the task content are; z < - 1.00485413 OR z > 1.00485413.
<h3>What is the solution to the given inequality?</h3>
It follows from the task content that the solution of the given inequality; ( 29 / 289z ) < ( 16 / 161 ) z is to be determined.
Since the given inequality is;
( 29 / 289z ) < ( 16 / 161 ) z
By cross multiplication; we have;
161 × 29 < ( 16z × 289z )
( 161 × 29 ) / ( 16 × 289 ) < z²
1.00973183 < z²
Therefore;
1.00485413 < z. OR. -1.00485413 > z.
Ultimately, z < - 1.00485413 OR z > 1.00485413.

Rewriting the expression we have:
(7 / (x ^ 2-7x)) - (5 / (x ^ 2-49))
Rewriting the denominator:
(7 / (x * (x-7))) - (5 / ((x-7) (x + 7)))
(1 / (x-7)) * ((7 / x) - (5 / (x + 7)))
Rewriting we have:
(1 / (x-7)) * (((7x + 49) + (-5x)) / (x * (x + 7)))
(1 / (x-7)) * ((2x + 49) / (x * (x + 7)))
((2x + 49) / (x * (x + 7) * (x-7)))
Answer:
The difference is:
((2x + 49) / (x * (x + 7) *(x-7)))
The third choice does not represent a proportional relationship because the y-intercept ≠ 0.
Hope that helped you.
