Me. i will give 100 point!
1) what is the solution to the system of equations?
2x+4y=122 x + 4 y = 12
y=1/4x-3y = 1 4 x − 3
a)(0.5, 5)
b)(5, 0.5)
, 8)
d)(8, -1)

2) what is the solution to the system of equations?
y=2x-3.5y = 2 x − 3.5
x-2y=-14
a)(7, 10.5)
b)(3.5, -7)
c)(10.5, 7)
, 3.5)

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.
