On a certain road segment, vehicle counts are taken every 5 min. On a particular day, the readings were zero at midnight, increasing continuously to reach a peak count of 432 at noon, and then decreasing continuously to zero again at the next midnight. Assuming the rate of increase from midnight to noon and the rate of decrease from noon to midnight to be constant, compute the PHF for t

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
