In order to solve the system of equations below, harvey multiplies each equation by a constant to eliminate the x terms.

7 x + 3 y = 5. 2 x + 5 y = negative 11.

what are the resulting equations?
14 x + 6 y = 10. negative 14 x minus 35 y = 77.
14 x + 6 y = 10. negative 14 x + 35 y = 77.
14 x + 6 y = 10. negative 14 x minus 35 y = negative 77.
negative 14 x minus 6 y = 10. 14 x + 35 y = negative 77.

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.

Perform the indicated operation and write the answer in the form a + bi. (-5 + 2) + (3 - 6i)
