Solve the system by the substitution method.11x – y = 29y = x2 – 1

Solve the equation by expressing each side as a power of the same base and then equating exponents. Only write the numerical value of the answer ( not x=)9x + 7 = 27x – 7

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 …
