Complete the square to rewrite y=x^2-6x+16 in vertex form. then state whether the vertex is a maximum or minimum and give its coordinates
a) minimum at (3,7)
b) minimum at(-3,7)
c) maximum at (-3,7)
d) maximum at (3,7)

Solve the system of equations y= 3/2 - 1, -x+ y =-3

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?

What is the equation of the line that is parallel to the line with the equation y= -3/4x +1 and passes through the point (12,-12)
