Answer:
lol its a little difficult for me but the answer is B
Step-by-step explanation:
The solution to a system of (linear) equations is the point where the graphs intersect. Consider two parallel lines. By definition, two parallel lines never intersect each other, but all pairs of non-parallel lines will eventually intersect. That means they will also have a solution.
Let's consider what makes a line parallel to another line. It basically looks identical, having the same steepness (slope), but the graph is just shifted over. That is, a parallel line would have the same slope and a different y-intercept. For our equation
, or
in slope-intercept form, a parallel line will be of the form
.
That describes the form of a parallel line, which we do not want. Any other line, however, will give a solution to our system, so we merely want a line where the slope does not equal 2.
We can have any equation of the form
.
Answer:
80x
Step-by-step explanation:
There is no substitution for the variable so the expression is 80x
Answer:
i don't know uhhhhhhhhhh do what ever you heart says
A. Both triangles equal 50 and 10x5 is 50. Therefore, y=5.
