9x - 3x = 2 + 10
6x = 12
so x = 2
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
Answer:
Third option:
Explanation:
The third option states that...
The graph crosses the y axis at (0,-5), which is correct. (0,-5) is the y-intercept of this graph.
The graph decreased from x=-10 to x=-2, which is also true. We can see a decrease starting from when x=-10 that ends when x=-2.
The graph remained constant from x=-2 to x=-10, which is correct. We do not see an increase or decrease on this graph from when x=-2 to when x=10.
I hope this helps! Please comment if you have any questions.
Answer:
Step-by-step explanation:
The standard algorithm is a way of doing multiplication by using partial products or multiplying in parts. What you do with this algorithm is multiply the top number by the bottom number one digit at a time, working your way from right to left.
