Suppose that the functions f and g are defined for all real numbers x as follows.
f (x)=x-1
g(x)=2x?
write the expressions for (f-8)(x) and (fog)(x) and evaluate (f+).
(-8)(x) = 0
(5-8)(x) = 0
x ó ?
(6+) = 1

On a piece of paper graph f(x)=5•(0.4)^x

Determine the fraction of total interest owed. after the fourth month of a 12-month loan: the numerator is: {(n + ) + (n + ) + (n + ) + (n + )} = , and the denominator is: {(n) + (n + 1) + + (n + )} = . therefore, the fraction is numerator/denominator (to the nearest tenth) =

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.
