Answer:
−(3x−2)(7x+4)
Step-by-step explanation:
The total amount Serena earns is the sum of her regular wage and the tips. The amount she earns from the wage is equal to 9h. This total should be more than or equal to $110. This is mathematically expressed as,
9h + 15 ≥ 110
3(3) - (-8)/4 = 9 + 2 = 11 so (3,-8) is solution
3(4) - 4/4 = 12 - 1 = 11 so (4,4) is solution
answer
