For the function f(x)=5x-6, determine whether f(x) is one-to-one. If so, (a) write an equation for the inverse function in the form y=f^-1(x), (b) graph f and f^-1 on the same axes, and (c) give the domain and the range of f and f^-1 . If the function is not one-to-one, say so.

The probability that you roll a two on a six-sided die is 1 6 16 . if you roll the die 60 times, how many twos can you expect to roll

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
