Solve the logarithmic equation. Be sure to reject any value that is not in the domain of the original logarithmic expressions. Give the exact answer. Do not write x=.log5(x – 3) = 2

Select the correct answer. The function A = A0e-0.01386x models the amount in pounds of a particular radioactive material stored in a concrete vault, where x is the number of years since the material was put into the vault. This is an example of …

Solve the system by the addition method. Determine the x-value of the solution to the system. 2x + 7y = -127x + 4y = -1

Solve.The function A = A0e-0.01386x models the amount in pounds of a particular radioactive material stored in a concrete vault, where x is the number of years since the material was put into the vault. If 500 pounds of the material are initially put into the vault, how many pounds will be left after 90 years? Round your answer to the nearest whole number. 

Solve the system by the addition method.x2 + y2 = 181×2 – y2 = 19

Graph the solution set of the system of inequalities or indicate that the system has no solution.2x – y ≤ -8x + 3y ≥ -9

Solve the system by the addition method. Determine the x-value of the solution to the system. 2x + 5y = 215x – 3y = -25

Solve the system by the method of your choice. Identify systems with no solution and systems with infinitely many solutions, using set notation to express their solution sets.y = 15 – 4x12x + 3y = 45

Solve the logarithmic equation. Be sure to reject any value that is not in the domain of the original logarithmic expressions. Give the exact answer. Do not write x=.log6(x + 3) = 1
