A is the set of factors of 15, B is the set of prime numbers less than10, then what is (AUB) a. {1,3,5,7 } b. {1,2,3,5} c. {1,2,3,5,7} d. {2,3,5}

Match each equation with the operation you can use to solve for the variable. subtract 10. divide by 10. divide by 5. subtract 18. multiply by 10. add 18. add 10. multiply by 5. 5 = 10p arrowright p + 10 = 18 arrowright p + 18 = 5 arrowright 5p = 10 arrowright

If y varies directly as x2 and y=6 when x=6, find the constant of variation.
