Answer:
Step-by-step explanation:
Because we are looking for the scale factor of the model to the bridge (model first), the scale factor will be less than one.
Each fraction () can be simplified to
. Therefore, the scale factor of the model to the bridge is
.
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!
