What is the equation of the circle with center (−13, −16) that passes through the point (−10, −16)? A)(x − 13)2 + (y − 16)2 = 9
B)(x + 13)2 + (y + 16)2 = 3
C)(x + 13)2 − (y + 16)2 = 9
D)(x + 13)2 + (y + 16)2 = 9

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.
