Step-by-step explanation:
I would help i really would but I need more info discussing the topic im sorry but I can't answer it
Answer: 7
Step-by-step explanation:
It's a 1 : 3 ratio so the answer should be 7
I think x would equal 7 because when y=75 and x=25, x is one third of y so one third of 21 is 7
Answer:
here is your answer!!!
Step-by-step explanation:
mark as brainliest and drop some thanks!!
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
