I would like some assistance with the steps to solve following calculus questions

\fCramer's Rule can be used to solve the following system of linear equations: 2x + 6y = -x - 3y = 4 Select one: O True O FalseThe exponential function h (a) = 9% is an increasing function. Select one: True O False X\fIf Cai = 5, then _ _1 (2a; + 7) = 38. Select one: True FalseThe production function for an oil well is given by the function B(t) = 100, 000e -0.2t, where B(t) is the number of barrels of oil the well can produce per month after t years. If the year t = 0 represents the year 2020, how many barrels of oil, to the nearest 100, per month can the well produce in the year 2030?
