Which quadratic function in vertex form can be represented by the graph that has a vertex at (-4,-3) and passes through the point (-6, -1)? Answer
A y = 1/2(x + 4)^2 - 3
B y = 2(x - 4)^2 - 3
C y = 1/2(x - 4)^2 - 3
D y = 2(x + 4)^2 - 3

Svetlana's hair is 4 4 centimeters ( cm cm) long. her hair grows 1 . 5 cm 1.5cm per month. svetlana wants her hair to be less than 1 6 cm 16cm long. write an inequality to determine the number of months, m m, svetlana can allow her hair to grow so that it is less than 1 6 cm 16cm long.

In the figure shown below, m < 40 and ab =8. which equation could be used to find x?

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.
