2. a rock is dropped from the edge of a 180 m
cliff. the function h(t) = -522 – 5t + 180
gives the approximate height of the rock, h(t),
in metres t seconds after it was released. how
long does it take for the rock to reach a ledge
80 m above the base of the cliff?

Solving systems of linear equations: tables represent two linear functions in a systemöwhat is the solution to this system? 0 (10)0 (1.6)0 18,26)0 18-22)

Which spreadsheet would be used to compute the first nine terms of the geometric sequence a^n=32•(1/2)n-1

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
