A)46. Take 42 and divide it by 3. Then multiply 14 by 4. b)2:1. There are 2 wings for every 1 beak on a bird. c)15 minutes. multiply 50 times 60 and that's how many times it beats per minute. Then divide 45000 by that number and that's how many minutes it should take. d) 28%. You have to add all the students together, and you get 200. Then you divide 56 by 200.
Step-by-step explanation: A fraction is undefined when its denominator is =0 or undefined. so we need to get 2/3x²-6=0 or undefined. so we can also do 3x^2-6=0. Solving yields ±√2!
Not a function because of the vertical line test. Domain is [-2,∞] since the left most point is -2 and the right is unbounded. Range is (-∞,∞) since it is not bounded in terms of y.
