I have school starting on monday and we received a packet for summer studying if we felt neccessary. Only problem is, I forgot a lot of the stuff I learned in Geometry and Algebra 2. Here are some sample problems I need to learn how to do...

Solve the following for x:

1.) -17/8x - 4/3 = 1

2.) 51/2x - 23/3x = 6



Solve each system of equations for x and y:

1.) { 4x-3y = -6
{ x+2y = -7

2.) { 19=5x+2y
{ 1=3x-4y


Compute the products:

1.) (3x² - 2a²)²

2.) [(a+b)-4] [(a+b)+4]


Factor the following:

1.) ab-bc+a²-ac

2.) 3x² - 22x - 16



Those are just some random problems I'm having trouble with.

This is not homework, it is only a summer study packet that should get me ready for class on monday.

Thanks for your help.

put in slope/y-intercept form identify the slope and the y-intercept

y=6

2x-1/2=y

y=5-x/5

y=2x/6-1/3

y=4x/-5

x+y=6

2x-y=0

3x+2y=6

y-x=-1

3x-y=1

x+3y=10

5x-2y+3=0

7x+3y=21

3x+9=0

3y-6=0

given f(x) = x^3 - 6x^2 + 9x and g(x) = 4
1) find the coordinates of the points common to the graphs of f and g
2) find all the zeros of f
3) If the domain of f is limited to the close interval [0,2], what is the range of f?

Pleas Help, thx in advance

Please Help Me
1) find the x-intercepts of the graph of f
2) write an equation for the tangent line to the graph of f at x = 2
3) Write an equation of the graph that is the reflection across the y-axis of the graph of f

can you guys give me the steps to solve these questions? my first question is :

given points A(-3, 2), B(6,8), and C(-4,6), determine the coordinates of a point D on the y axis so that CD is parallel to AB.

i dont really know what to do after finding the slope?

and this other question i dont get.

Find the value of k if the slope of kx-3y= -9 is 1/9

thanks loots

I'm having a trouble solving these two problems on my calculus summer assignment:

simplify: [ (1/x) - (1/5) ] / [ (1/(x^2)) - (1/25) ]

rationalize the denominator: 1 / ( 1 + √3 - √5 )

Please provide an explanation on how to approach and solve the problems... Thank you.
