X^2+8x+6+2/x+4 am i right ??
x = [-(-6) +/- sqrt((-6)^2 - 4*1 * 8))] / 2
= (6 + sqrt4) / 2 , ( 6 - sqrt4)/2
= 4 , 2
Answer: Yes!
Explanation: There are only one y coordinates per x coordinate :)
Let me attach a helpful picture too:
The operator
is transitive, which means exactly that

That's the only thing you can deduce from your statement.
We are given the data that David has been reimbursed with $3390 driving 600 miles and his expenses are <span>$60 a day for food and lodging and $0.65 per mile. The equation is 3390 = 60 x + 0.65 * 600 = 60 x +390 where x is the number of days. To determine x, we transpose 390 to the other side and divide the equation by 60. x is equal to 50 days.</span>
