Tree B is 4 feet tall and grows 8 inches per year.
Which equation represents the year, x, when the height of the trees are the same?

A
2x+43=4x+23

B
43x+2=23x+4

C
2x+16=4x+8

D
16x+2=8x+4

Which term best describes the association between variables a and b? no association a negative linear association a positive linear association a nonlinear association a scatterplot with an x axis labeled, variable a from zero to ten in increments of two and the y axis labeled, variable b from zero to one hundred forty in increments of twenty with fifteen points in a positive trend.

If f(x) = 4x – 3 and g(x) = 8x + 2, find each function value a.f[g(3)] b.g[f(5)] c.g{f[g(-4)]}
