Question 109719: this one is tough.. you are making a coffee table with a glass top surrounded by a cherry border. The glass is 3 feet by 3 feet. You want the cherry border to be uniform width. you have 7 square feet of cherry to make the border. set up an equation that would be used to solve this. what should the width of the border be?
if you could please help me.. it would be greatly appreciated :]

Question 109999: Ok. so this one is a graph of a positive, even parabola which means it opens up. the vertex is (-1,-2) and one of the points on the parabola is (0,-1). It's telling me to write a quadratic function in vertex form for the parabola. what is vertex form and how do i plug in the coordinates to find it? HELP PLEASE! :]

Question 112971: I am in algebra 2 and we are learning about "interperetting graphs. Equations like, "If f(x)=Xsquared the the graph of each equatrion below is a parabola. Describe the location of the parabola relative to the graph of f(x)=xsquared.... y=f(x)-3 or y=f(x-2)" im so lost, we have a sustitute because our teacher is on meternity leave on he knows nothing about anything he is teaching. Please help!

Question 115162: Consider the function fx = x^ +6x - 2
1- Find h, the x-coordinate of the vertex of this parabola.
2 - Substitute the two whole number values immediately to the left and right of h into the function to find the corresponding y. Fill in the table below. Make sure your x-values are in increasing order in your table.
x y
h=__
I do not comprehend the equation/function/graph thing......can someone give me a look at how to do problems like this? Thanks - I have 3 more like it to do this week.
