The question is in the picture please help if can I will be really grateful
1 answer:
The factor (x-9) is negative for x < 9. It is zero for x = 9.
The factor (7x+2) is negative for x < -2/7.
The factors have different signs for -2/7 < x < 9. When their signs are different, their ratio is less than zero. When x = 9, the ratio is equal to zero.
The appropriate choice is the graph that shows -2/7 < x ≤ 9.
