Four times a number is equal to negative eight.
We can write the following proportion between the milligram and milliliters:

Solving for x, we have

Intuitively, the original 1000mg/250ml solution tells us that the number of milliliters is one fourth of the number of milligrams.
So, if we want 700mg, we have one fourth of this value for the milliliters:

Answer:
First triangle
Step-by-step explanation:
First triangle is the obtuse triangle.
<h3>You should pick:</h3>
The relationship is linear because each y-value is 5 more than the one before it.
<h3>Here's why I think so:</h3>
If we look at the relationship between the x values and the y values, we can tell that they both increase periodically. The x values increase by 1('s), while the y values increase by 5('s).
Think about it. If y starts off at 5 when x is at 0, and then goes to 10 by x becomes 1, and increases another 5 values when x increases by 1 (again), then we are witnessing a pattern. For every 1 x value, y increases by another 5 values. Such a repetitive relationship will clearly be shown with a line. Thus, the relationship is a linear one.
Since we know that the relationship of the table is linear, and that it is linear due to the fact that the y-value continuously increase by 5's without fail, the only answer that would make sense is the second one.
<em>Therefore, the answer is '</em><u><em>The relationship is </em></u><u><em>linear </em></u><u><em>because each y-value is 5 more than the one before it.</em></u><em>'</em>
