Consistent means 1 solution
inconsistent means no solutions....because they are parallel lines
equivalent means infinite solutions...because they are the same line

y = 3x - 2             3x - y = 4
                            -y = -3x + 4
                             y = 3x - 4

both equations have the same slope but different y intercepts....this means they are parallel lines and have no solutions ....INCONSISTENT
=======================
1/2y = -x + 5                  2y = -4x + 20   
y = -2x + 10                     y = -2x + 10

same equation.....same line...infinite solutions...EQUIVALENT
===================
y = -x + 4               x = -y - 6
                              y = -x - 6

same slope, different y intercepts....parallel lines......no solutions...this means INCONSISTENT
==================
y = 4x + 2                y = 6x - 10
different slopes, different y intercepts...one solution...CONSISTENT
==================
y = 2x + 1               y = -2x + 3
different slopes, different y intercepts...one solution...CONSISTENT
=================
-2x + 5y = 0              y = 2/5x
5y = 2x
y = 2/5x
same line....infinite solutions....EQUIVALENT

16)<br> 1420<br> 2x<br> A) 67<br> C) 68<br> B) 71<br> D) 73<br><br> What is the value of x???
larisa [96]

Answer:

x = 710

Step-by-step explanation:

1. Divide both sides by 2 to get x by itself

1420 = 2x

↓

1420 ÷ 2 = 2x ÷ 2

↓

710 = x

2. Switch sides

710 = x

↓

x = 710

I know it is not one of your options but that is the answer to 1420 = 2x
