ALGEBRA
Solve the inequality. (Enter INFINITY for infinity and -INFINITY for -infinity as needed.) 6<=5 - y

ALGEBRA
Solve the equation. (Enter solutions from smallest to largest. If there is no solution, enter NONE in the answer boxes.) x2 - 5x + 5 = 0 x = x =

ALGEBRA
Write the expression in terms of common logarithms, and then give a calculator approximation (correct to four decimal places). log_(7) \(80\)

ALGEBRA
Contract the expressions. That is, use the properties of logarithms to write each expression as a single logarithm with a coefficient of 1. text((a) ) ln\(3\)-2ln\(4\)+ln\(8\) text((b) )ln\(3\)-2ln\(4+8\) text((c) )ln\(3\)-2(ln\(4\)+ln\(8\))

ALGEBRA
Use the definition of logarithm to simplify each expression. text((a) )log_(3b) \(3b\) text((b) )log_(4b) \((4b)^6\) text((c) )log_(7b) \((7b)^(-11)\)

ALGEBRA
The velocity v (in feet per second) of a rock dropped into a well is related to time (in seconds) by the formula v = 32t. What is the velocity of the rock at the indicated instant? Write your answer in the form (t, v). (a) when the rock is released ( , ) (b) after 9 seconds
