Write always, sometimes or never, a conjecture is true

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

Use composition to determine if (x) or h(x) is the inverse of f(x) for the limited domain x2-1.

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?
