Y=1/2x+4 and 2y+4=x so substitute y into the second equation to get
2(1/2x + 4) =x
use the distributive property to get x + 8 = x. There is no solution to this equation because x + 8 cannot equal x, and because of this you cannot solve the rest of it so there is no solution.
C.
4 (x+7) = 38 represents the tape diagram correctly.
Answer and Step-by-step explanation:
1) If you graph the lines, you will get the lines in the first attachment. You will see that the intersection point is (3, 5), which is the solution to that system.
2) First, let's convert both of these into slope-intercept form so that they're easier to graph.
x - 3y = 2
x = 3y + 2
3y = x - 2
y = 
AND
-3x + 9y = -6
9y = 3x - 6
y = 
We see that these two lines are exactly the same, which means that no matter what coordinate works for one, it will work for the other. In other words, there are infinitely many solutions.
And, if you graph these lines, you will get the graph in the second attachment, where they are the same line.
Hope this helps!
Answer:
y = -1/2x + 4
Step-by-step explanation:
I got -1/2x because for every 2 spaces, the line goes down 1 (rise/run)
I got +4 because 4 is where x = 0, or the y intercept
2.5 /10 = 10 / x
100 = 2.5x
40 =x
