The ratio of the number of Ali's pens to the number of Marks pens was 2:3 at first. After Dad gave Ali another 16 pens, the ratio became 2:1. How many pens did Mark have? If Mark gave away 6 pens, what would the new ratio of Ali's pens )after Dad gave her 16 pens) to the number of Mark's pens?

The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 −5 0 −1 1 3 g(x) g(x) = 2x − 7 part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points) part b: which function has a greater y-intercept? justify your answer. (4 points)

For which pairs of functions is (f•g)(x)=12x? f(x)=3-4x and g(x)=16x-3 f(x)=6x2 and g(x)= 2/x f(x)= and g(x) = 144x f(x)=4x and g(x) =3x
