A linear equation represents a straight line.Thus, the solution of the system of linear equation depends on whether the lines intersect, not intersect or same line.
We have below cases:-
- The lines are non parallel and intersect at exactly one point. In this case we have one solution.
- The lines are parallel and hence never intersect. There is no solution in this case.
- The two lines represents the same line. Hence, infinitely many solutions.
We never got exactly two solutions because two lines can intersect at a single point.
The slope is 0.5 tablespoon per minute, which you can deduct from the increase of y from one minute to the next.
The initial value (at x=0) is 1. So the equation is:
y = 0.5x + 1. That's the last one in the list, answer D.
You can think of it as two separate fractions. 1/2 divided by 3/1. You can solve this by multiplying the first fraction by the reciprocal of the second fraction. A reciprocal is switching the fraction by turning it over. So you just have to solve 1/2 multiplied by 1/3. As a result you get 1/6 as the answer! Hope this helped!
Answer:
Step-by-step explanation:
The segments formed by the parallel lines are proportional segments.
