Answer:
Lin
Step-by-step explanation:
5/7*2/2=10/14
3/2*7/7=21/14
10/14+21/14=31/14
The domain is equal all real numbers

The degrees of the polynomial is odd (3x^7, 7 is odd), therefore the range is equal all real numbers
Answer:
460 USD
Step-by-step explanation:
monthly earnings = 250 x 4 = 1000
monthly bills = 135 x 4 = 540
end of month = 1000 - 540 = 460 USD
Answer:
R= {7, 11, 15}
Step-by-step explanation:
Since we already know what the Domain is for f (2, 4, 6) we can use that to get the range
Since the domain is also x let's replace x for 2
y=2(2)+3= 4+3=7
One of the range is 7
Replace x for 4
y=2(4)+3= 8+3= 11
One of the other range is 11
Replace x for 6
y= 2(6)+3= 12+3= 15
The last range is 15
So the range is R= {7, 11, 15}
The answer is n^4. This is calculated by just subtracting the exponents. Hope this was what you were asking.
