a: slope=3; y-intercept=3
b: slope=0; y-intercept=3
c: undefined slope; y-intercept=0
d: undefined slope; y-intercept=3

Element x decays radioactively with a half life of 8 minutes. if there are 450 grams of element x, how long, to the nearest tenth of a minute, would it take the element to decay to 37 grams?

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)

Using elimination, what is -4x+2y=-12 4x+8y=-24
