Answer:
- Q6. x = 17
- Q8. Yes, parallel
- Q9. No, not parallel
Step-by-step explanation:
Q6. Solve for x
<u>Use ratios of similar sides</u>
- 28/(82 - 28) = (2x + 8)/(5x - 4)
- 28/54 = (2x + 8)/(5x - 4)
- 14/27 = (2x + 8)/(5x - 4)
- 14(5x - 4) = 27(2x + 8)
- 70x - 56 = 54x + 216
- 70x - 54x = 56 + 216
- 16x = 272
- x = 272/16
- x = 17
Q8
If ratios are same, the lines are parallel
- 41.8/33 = (102 - 45)/45
- 41.8/33 = 57/45
- 41.8*45 = 33*57
- 1881 = 1881
Yes, lines are parallel
Q9
Incorrect, lines are not parallel

The formula you use to calculate this is: FV=PV(1 + R)^N, where FV=Future value, PV=Present value, R=Interest rate per period, N=Number of periods.
Answer:
x<7 or x>1
Step-by-step explanation:
The given inequality is
|x-4|<37
By the definition of the absolute value function, we get
x-4<3 or -(x-4)<3
We divide both sides of the inequality on the right by -1 and reverse the sign.
x-4<3 or x-4>-3
We add 4 to both sides of the equation to get:
x-4+4<3+4 or x-4+4>-3+4
x<7 or x>1
