Algebra 2
Can someone please explain to me how to solve logarithmic equations? Some examples are: -5=log2X 3^5x+1= 40 and log6X+(log6)7=(log6)35 I hope that makes sense because logs are hard to type.

1. If y varies directly as x, and y=30 when x=4, find the constant of proportionality. 2. If y varies inversely as x, and y=2 when x=10, find x when y=4. 3. If a varies jointly as b and c, and a=-10, when b=12 and c=2, find a when b=8 and c=1/2.

Solve: (2x – 3)(3x – 5) = 0 Solve by the quadratic formula. Leave the square root in your answer: 3x2 – x – 8 = 0

How do you find the vertex of a quadratic function? What are the steps to solving a quadratic function using factoring? Please help!

Algebra II repost- please check
I posted these a little while ago but this time I have answered them. 1. Does the graph of y = x – 3x2 + 5 have a maximum or minimum? 2. What is the vertex of the graph of y = -2(x - 3)2 + 4? 3. Does the graph of y = -2(x - 3)2+ 4 open up or down? My answers: 1. I cannot ...
