You need to find x first but it has to be x×x-4x
Answer:
y = 1
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = 25 when x =
, then
25 =
= 5k ( divide both sides by 5 )
5 = k
y =
← equation of variation
When x = 5, then
y =
= 1
The polynomial is the same in standard form
9|⁻¹/₃z| + 6 < 30
9|⁻¹/₃z| + 6 < ±30
9|⁻¹/₃z| + 6 < 30 or 9|⁻¹/₃z| + 6 > -30
9(¹/₃z) + 6 < 30 or 9(¹/₃z) + 6 > -30
3z + 6 < 30 or 3z + 6 > -30
- 6 - 6 - 6 - 6
3z < 24 or 3z > -24
3 3 3 3
z < 8 or z > -8
Solution Set: {z|z < 8 or z > -8} and (-∞, 8) or (-8, ∞)

Sorry if im wrong but im sure the second one is correct
