Find the slope. is it positive, negative, zero or undefined? show your work. y=-1/8x+12

In the 30-60-90 triangle below side s has a length of and side r has a length

The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable

Use the elimination method to solve the systems of equations.choose the correct ordered pair. 7x+4y=39
