Rectangle QRST has coordinates Q(-3, 7), R(-3, 11), S(4, 11), and T(4,7) Dilate the rectangle by a scale factor of 3 with a center of dilation at the origin. What are the coordinates of rectangle Q’R’S’T’? Explain your reasoning. Is the dilation a reduction or an enlargement?

Negative 5 1/12 + negative 4 1/4 + 6 3/4

Need solving this 2nd limit problem.

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.
