Which of the following systems is dependent? x − y = 2 and x + y = −2 x − y = 2 and −2x + 2y = −4 x − y = 2 and 3x − 3y = 2 x −
hram777 [196]
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:
 x - y = 2

-2x + 2y = -4
 Let's rewrite the system of equations.
 To do this, let's multiply equation 1 by scalar -2:
 -2x - (-2) y = (-2) 2

-2x + 2y = -4
 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

Answer:

See below

Step-by-step explanation:

q = quarters       value   = .25 q

n = nickels =  4q     value = .05 (4q)

    summed = 12.60

<u>.25q   + .05(4q) = 12.60  </u>    <====== <u>can be used to solve the problem</u>

.45q = 12.60

<u>q = 28     quarters     then nickels = 4q = 112  </u>
