Ineed with my math problem- this might be cheating but eh (it is) anyways- my question is: evaluate 3+11t -9u3+11t−9u3, plus, 11, t, minus, 9, u when t=9t=9t, equals, 9 and u=11u=11u, equals, 11. (sorry this is- complicated.)

Paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each? 1. define a variable for the situation. 2. write an inequality that represents her profit. note: revenue is money coming in. cost is money going out. profit is the difference between the revenue and the cost. in other words: revenue - costs profit 3.using words, describe how many windows she must sell to have a profit of at least $48,000.

At store a, erasers are sold individually. the cost y of x erasers is represented by the equation y=0.75x. the costs of erasers at store b are shown in the graph.

If 5x - 2 = -12, then x = a) -50 b) -4.4 c) -2.8 d) -2
