Answer:
y =
Step-by-step explanation:
Since y is inversely proportional to x the equation relating them is
y = ← k is the constant of proportionality
To find k use the condition when y = 7, x = 9
k = yx = 7 × 9 = 63
y = ← equation connecting x and y
Answer:
7(x+4)-2/3 (x-6) < 2[x-3(x+5)]
Do it 1 step at a time.
7(x+4)-2/3 (x-6) < 2[x-3x-15]
7x+28 - 2/3 (x-6) < 2[x-3x-15]
I'll assume you mean (2/3)*x-6)
---
7x+28 - (2x/3) - 4 < 2[-2x-15]
7x+24 - (2x/3) < -4x-30
Add 4x
11x+24 - (2x/3) < -30
Add 30
11x + 54 - (2x/3) < 0
Multiply thru by 3
33x + 162 - 2x < 0
31x < 162
x < 162/31
