Use the elimination method to solve the system of equations?<br> 6x+2y=8<br> 12x+y=22

Xelga [282]

The solution is: x=2, y=-2

Step-by-step explanation:

Given equations are:

6x+2y=8 Eqn 1

12x+y=22 Eqn 2

Multiplying Eqn 1 by 2

$2(6x+2y)=2(8)\\12x+4y=16$ Eqn 3

Subtracting Equation 2 from eqn 3

$12x+4y-(12x+y)=16-22\\12x+4y-12x-y=-6\\3y=-6\\Dividing\ both\ sides\ by\ 3\\\frac{3y}{3}=\frac{-6}{3}\\y=-2$

Putting y=-2 in eqn 2

$12x-2=22\\Adding\ 2\ on\ both\ sides\\12x-2+2=22+2\\12x=24\\Dividing\ both\ sides\ by\ 12\\\frac{12x}{12} = \frac{24}{2}\\x=2$

The solution is: x=2, y=-2

Answer:

a. 2/5; reduction

Step-by-step explanation:

It appears that C is the center of dilation, so C' and C are coincident. The scale factor is ...

P'C'/PC = 4/10 = 2/5 . . . scale factor

The scale factor is less than 1, so the dilation is a <em>reduction</em> in size.
