Answer:
6 minutes
Step-by-step explanation:
every minute is 120
720/120=6
To solve this, set up two equations using the information you're given. Let's call our two numbers a and b:
1) D<span>ifference of two numbers is 90
a - b (difference of two numbers) = 90
2) The quotient of these two numbers is 10
a/b (quotient of the two numbers) = 10
Now you can solve for the two numbers.
1) Solve the second equation for one of the variables. Let's solve for a:
a/b = 10
a = 10b
2) Plug a =10b into the first equation and solve for the value of b:
a - b = 90
10b - b = 90
9b = 90
b = 10
3) Using b = 10, plug it back into one of the equations to find the value of a. I'll plug it back into the first equation:
a - b = 90
a - 10 = 90
a = 100

Answer: The numbers are 100 and 10</span>
The best answer is A. The possible roots of this polynomial function 9i and -9i. It is possible that this polynomial function is a quadratic equation. It has a degree of two which means there are two roots and it is possible that the positive and negative value of 9i are its roots.
