It's the one second below the question because it does not have two outcomes for x. For example in a relation x could result in y = 2 or y = -2.
Hope this helps! :)
Answer:
Step-by-step explanation:
<u>Direct variation equation:</u>
- y = kx, where k is constant of variation
<u>Given:</u>
<u>The equation is:</u>
<u>Find the value of x when y = 168:</u>
- 168 = 12x
- x = 168/12
- x = 14
If you plot them you will see that the intersect each other in two different points.
The solution of a system of equations is the set of points of intersection of the graphs of the equations.
The answer is D.
