Imagine what the graph would look like. Does it open upwards or downwards?
5x - 1 has a positive slope of 5 and it is reflected horizontally. The graph would be shaped like a V. A limited segment, or none, of the graph is below a certain value of y, and the rest outside it is above.
Hence, the solution must be a < x < b.
|5x - 1| < 1
5x - 1 < 1
x < 2/5
|5x - 1| < 1
5x - 1 > -1
x > 0
0 < x < 2/5
Answer:
x = ± 2
Step-by-step explanation:
Given
16 - 2x² = - 64 ( subtract 16 from both sides )
- 2x² = - 80 ( divide both sides by - 2 )
x² = 40 ( take the square root of both sides )
x = ± 
= ± 
= ± 2
