Δ LMN and Δ LJK are similar triangles, so the ratios of corresponding sides are equal, that is
= , substitute values
= = ( cross- multiply )
2x = x + 9 ( subtract x from both sides )
x = 9
B, because the first graph shows a rate of 35 mph. We don’t want that. Answer c states, that the rate is constant however that is not true. B is the only equation showing that if you plug in any x for the number of hours, you will get your answer. Therefore b is your answer! Hope this helps
