I recently completed a test and got these Algebra questions right. (I am really good at math) So I chose to make a forum to see if anyone can get any of these algebra 2 equations and questions right! (6 Questions total) Problem 1: Solve the equation 5(-3x - 2) - (x - 3) = -4(4x + 5) + 13 Problem 2: Simplify the expression 2(a -3) + 4b - 2(a -b -3) + 5 Problem 3: (hint: If x <2, simplify) |x - 2| - 4|-6| Problem 4: (hint: SUBTRACT THEM!!!) Find the distance between the points (-4 , -5) and (-1 , -1). Problem 5: (Hint: Find the x intercept of the graph of the equation) 2x - 4y = 9 Problem 6: Evaluate f(2) - f(1) #### = 6x + 1

ill just do this one

2(a -3) + 4b - 2(a -b -3) + 5

= 2a - 6 + 4b - 2a -2b -6 + 5
=2a - 2a + 4b -2b + 5 - 6 - 6
=2b - 7

am i right

5(-3x - 2) - (x - 3) = -4(4x + 5) + 13


-15x-10-x+3=-16x-20+13
-16x-7-x=-16x-7
0=0

I'll solve a few of them to help you out a bit.

Problem 1:

5(-3x - 2) - (x - 3) = -4(4x + 5) + 13
(-15x - 10) - (x - 3) = (-16x - 20) + 13
-15x - 10 - x + 3 = -16x - 20 + 13
-16x - 7 = -16x - 7

Answer : Infinitely many solutions

Problem 2:

2(a - 3) + 4b - 2(a - b - 3) + 5
2a - 6 + 4b - 2a + 2b + 6 + 5
6b + 5

Problem 3:

Assuming it's asking you to simplify an expression

|x - 2| - 4|-6|
|x - 2| - |-24|
|x - 2| - 24

Assuming it's asking you to solve for x

|x - 2| - 24 = 0
|x - 2| = 24

x - 2 = 24
x = 26

x - 2 = -24
x = -22

Problem 4:

This is asking you to use distance formula which is:

d = √( (x2 - x1)^2 + (y2 - y1)^2 ) for coordinates (x1, y1) and (x2, y2), and where ^ denotes an exponent.

You can apply it like so:

d = √( (-1 - (-4))^2 + (-1 - (-5)^2) )
= √( (-1 + 4)^2 + (-1 + 5)^2 )
= √(3^2 + 4^2)
= √(9 + 16)
= √(25)
= 5

Problem 5:

The x-intercept occurs at y = 0, so you can insert 0 into the equation for y to find the x-intercept and then simplify

2x - 4(0) = 9
2x = 9
x = 4.5

Problem 6:

Some of this is blocked out so I can't help you.

Oh wait, you didn't need homework help. You were challenging us haha.

Anyways, these are NOT "Algebra 2" questions, these are more Pre-Algebra questions.
