A study in the Los Angeles Times reported that the number of liquor stores in a neighborhood has a strong positive linear association with the amount of crime in that neighborhood. What can you determine about the relationship between the number of liquor stores and the amount of crime?

a. Neighborhoods with a higher number of liquor stores tend to have a higher amount of crimes.
b. If we decrease the number of liquor stores in a neighborhood, the amount of crimes will decrease.
c. No conclusions can be drawn without seeing a scatterplot of the data.
d. People who live in neighborhoods with more liquor stores commit more crimes.

Find the zero function by factoring (try to show work) h(x)=-x^2-6x-9

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
