Step-by-step explanation:
The number of tickets sold by Dan the first day is x.
Tickets sold on the 2nd day: x+3
on the 3rd day: x+6
on the 4th day: x+9
on the 5th: x+12
Since the total of tickets sold by Dan is 40:
x+(x+3)+(x+6)+(x+9)+(x+12)=40
5x+30=40
5x=10
x=2
number of tickets sold on the third day: 8
Answer:
iv ; xy + x/y = 3
Step-by-step explanation:
A non linear equation is one in which there is no product of two different variables or the same variable
What this mean is that we have the highest polynomial power as 1 or we simply have polynomials of degree 1
Looking at the given options, we can see the product xy
What this mean is that the polynomial is of degree 2 and that makes the equation a non linear as we have a polynomial of more than 1 degree
