She swims for 2.5 hours at a rate of 2 km/hr
Multiply 2.5 * 2 = 5 km
Answer:
6:20 PM
Step-by-step explanation:
They got there at 8:30 PM, and 2 hours and 10 minutes prior would have been 6:20 PM.
The answer to that is (x^4 y^6+1)(x^8 y^12-x^4 y^6+1
A system is linearly dependent, when multiplying one of the equations by a scalar, you get the other equation.
We then have the following system of equations:

Let's rewrite the system of equations.
To do this, let's multiply equation 1 by scalar -2:

We observe that we obtain equation 2 of the system.
Therefore, the system is linearly dependent.
Answer:
the following system is dependent:
x - y = 2 and -2x + 2y = -4
