Interpretation of the vertical line

If only one vertical line intersects the graph at exactly one point, the graph represents a function. If only one vertical line intersects the graph at exactly one point, the graph does not represent a function. If any vertical line can intersect the graph at more than one point, the graph represents a function.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
