Use a recursive function for the geometric sequence 2, −8, 32, −128, … to represent the 9th term.
a: f(9) = f(1) + −4(8)
b: f(9) = f(8) + −4(8)
c: f(9) = f(1) • (−4)8
d: f(9) = f(8) • (−4)

Lois and clark own a company that sells wagons. the amount they pay each of their sales employees (in dollars) is given by the expression 12h+30w12h+30w where hh is the number of hours worked and ww is the number of wagons sold.

Jim makes $10.35 per hour. write an equation that jim can use to calculate his pay.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
