• last week, lindsay earned $10 per hour plus a $60 bonus for good job performance. she spends of her paycheck on dinner with friends. if she had not earned the bonus, the amount she spent on dinner would have been of her paycheck. which equation can be used to find h, the number of hours lindsay worked last week?
  
• which lines describe the ice wrapping the tree branches? as the breeze rises, and turn many-colored as the stir cracks and crazes their enamel. soon the sun’s warmth makes them shed crystal shells shattering and avalanching on the snow-crust— but swinging doesn’t bend them down to stay. ice-storms do that. often you must have seen them such heaps of broken glass to sweep away you’d think the inner dome of heaven had fallen.

• the curve produced by the water coming from a hose is sketched onto a graph with zeros at 0 and 5. the point (4, 1) also lies on the curve. if h(x) represents the vertical distance from where the water first comes out of the hose and x represents the horizontal distance, which statements are true? check all that apply. the scenario can be represented by the function h(x) = –0.25(x)(x – 5). the scenario can be represented by the function h(x) = (x)(x + 5). the vertex is on the line x = 2.5. the greatest height that the water reaches is 1.5 units. the scenario can be represented by the function h(x) = –1(x – 5).
