Please help with Algebra?

I need help with this assignment thing, I am a senior and terrible at math, this shouldn't be hard for anyone who is good at math. It's only Algebra 1. I need to pass this class to graduate and right now I'm barely passing with a C. At most schools a D is considered passing but at mine it's failing. ): Please please please help. I've gone to math tutors and everything I just don't understand it!

1.

The equations of four lines are given. Identify which lines are parallel.

Line 1: y = mc002-1.jpgx + 5

Line 2: x + mc002-2.jpgy = 8

Line 3: y = mc002-3.jpgx – 9

Line 4: y + 9 = mc002-4.jpg(x + 9)

C) Lines 1 and 4 are parallel.

D) Lines 2 and 3 are parallel.

2.

C) mc008-16.jpg and mc008-17.jpg are perpendicular.

D) mc008-18.jpg and mc008-19.jpg are perpendicular; mc008-20.jpg and mc008-21.jpg are perpendicular.

4.

Identify the lines that are perpendicular:

mc011-1.jpg; mc011-2.jpg; mc011-3.jpg; mc011-4.jpg

A) None of the lines are perpendicular.

B) mc011-14.jpg and mc011-15.jpg are perpendicular.

C) mc011-16.jpg and mc011-17.jpg are perpendicular.

D) mc011-18.jpg and mc011-19.jpg are perpendicular; mc011-20.jpg and mc011-21.jpg are perpendicular.

5.

Write an equation in slope-intercept form for the line parallel to y = mc013-1.jpgx – 9 that passes through the point (–9, –9).

A) y = mc013-9.jpgx – 9

B) y = mc013-10.jpgx – mc013-11.jpg

C) y = mc013-12.jpgx – mc013-13.jpg

D) y = mc013-14.jpgx + mc013-15.jpg

6.

Write an equation in slope-intercept form for the line perpendicular to y = mc014-1.jpgx – 9 that passes through the point (–5, –9).

A) y = mc014-9.jpgx – mc014-10.jpg

B) y = mc014-11.jpgx – mc014-12.jpg

C) y = mc014-13.jpgx – 9

D) y = mc014-14.jpgx + mc014-15.jpg

7.

Write an equation in slope-intercept form for the line perpendicular to y = mc019-1.jpgx + 9 that passes through the point (4, 9).

A) y = mc019-9.jpgx + 9

B) y = mc019-10.jpgx – mc019-11.jpg

C) y = mc019-12.jpgx + mc019-13.jpg

D) y = mc019-14.jpgx + mc019-15.jpg

    I want to help you, but I am not understanding what you wrote. email me at canni19@yahoo.com

    First of all - realize, no one can read your question (all the (pictures, I'm assuming, due to the .jpgx's?) are not showing up, so we have no idea what you are asking)

    Second of all - this looks extremely easy, even for someone who is a senior in Algebra 1

    Third of all - I can understand when someone needs a tutor in Algebra 2 or above - but maybe you should try a different tutor, or BETTER YET, study!!! - Some people say you don't have to study in math, but those are people to whom it comes naturally - you CAN study by PRACTICING..... if you have someone else do your homework for you, you will learn absolutely NOTHING, therefore will not be able to pass any test, thus earning a measly D/F in your low level class - all you need to do is do your OWN homework, working at it until YOU (not someone who is explaining it to you) understand it

    Anyway, hope you'll take my advice and can raise your math grade up to a respectable level :D

    if not, you get what you work for right?

    For increasing cubic binomials the final formula is as follows: (a + b) ^ 3 = a^3 + 3*a^2*b^a million + 3*a^a million*b^2 + b^3 on your case, a is x and b is -y^5 So (x - y^5)^3 = x^3 + 3*x^2*(-y^5)^a million + 3*x^a million*(-y^5)^2 + (-y^5)^3 Simplified: =x^3 - 3x^2*y^5 + 3x*y^10 - y^15 :D

  • Jpg is a picture extension of a file name. Why you are using such in your math??

    Get the question straight, ask how to do the question rather than what the answers are,

    and pose one general question rather than many.
