It says that you need to divide 2 exponents with the same base, you keep the base and subtract the powers, its kind of like reducing fractions! :)
Answer: Choice A
The domain is the set {-5, -3, 1, 2, 6} which can be written as {x| x=-5, -3, 1, 2, 6} if you want to make it clear that x is involved with the domain.
------------------------------------------------------------------
Explanation:
The domain is the set of x values, or the set of inputs, of a function or relation. All you have to do is list off the values in the "input" oval. Those values from top to bottom are: -3, 2, -5, 1, 6. Sort them out from smallest to largest and you get -5, -3, 1, 2, 6 which points us to choice A.
Another route you could go is eliminating choices B, C and D because -9 is not in the "input" oval.
If my maths are correct it would be $3,000
Answer:
answer is definitely A!!
Step-by-step explanation:
Ron’s class donated d dollars to a local charity.
=> Let's use d as an expression of the donation of Ron's class.
Danny’s class donated 21% more than ron’s class.
Let's show this into expression
Expression:
=> 21% / 100% = 0.21
Danny's Class donation=> d + d(.21), where d is the amount of the donation of Ron's class and 0.21 is the 21% of Danny's class
