1. can't be determined cause no info given on the rate of which the population is growing.
2. can't be determined/not true because the initial population of a could be less than b.
3. can't be determined/not true because we don't have enough info to tell how fast they grow and decline.
Answer:
2 : 5
Step-by-step explanation:
Answer: 20
Step-by-step explanation:
Follow order of operations (PEMDAS)
20÷1÷[(10÷5)÷2] Given
20÷1÷[(2)÷2] Do 10÷5 in parenthesis
20÷1÷[(1)] Do (2)÷2
20÷1 Do 1÷[(1)]
20 Do 20÷1, and that is your answer
Answer:
6 units
Step-by-step explanation:
Think about this. What do the numbers in a coordinate stand for? They stand for X and Y. If you're trying to figure out what the X is, wouldn't you be solving for x? And didn't they just give you an equation? ;) First off, do you see how the "Y" value is given to you in the coordinate? All you have to do is substitute that 3 in for the "y" in the equation! 3=2x+5. Hey.... that looks like a simple equation! First, you need to subtract 5 from the other side of the equation. Now you're left with 2x=-2. Divide both sides by 2, and you get that x=-1. Now, just substitute that "x' value into the coordinate, and your answer should come out to be (-1, 3). :D
