Question 698651: Hello,
I have a test on Monday and am doing some practice problems for a study guide right now, but am stuck on this one:
-x-4>3x-2
So far I have done this:
-x-4>3x-2
2x-4>-2
2x>-2
x>1
When I went to go check my work, the answer was wrong? Can you please help?
Thank you so much in advance!

Question 698592: A. Construct a table of values for y < -x². Use -2 ≤ x ≤ 2
I have made my table.
x| y<-x²|y
------------
-2|-(-2)²|-4
------------
-1|-(-1)²|-1
------------
0| -(0)²| 0
------------
1| -(1)²|-1
------------
2| -(2)²|-4
------------
B. In the space at the right, draw the graph y < -x².
I graphed the shaded area already. All I need help on is C. Thank you
C. Check your graph by verifying a point in the shaded area.
I have no idea how to do this and this is like my last problem of my last exam in algebra.

Question 699439: Ok my question is about graphing of linear inequalities but I don't know what to do you see I have a question that's ask me to describe and correct the error in the graph of the inequality that o was given the question is Y is less then or equal to two X plus two then it is graphed and is shaded on the top of the line I don't see what's wrong it is doted on (-2,-2) (0,-1) (2,0) (4,1) could you please help me I'm completely lost thanks a lot :)

Question 699759: i need to understand how to turn equations into slope-intercept form, point-slope form, and standard form. I realise i can use a graph but in which case i dont have one. Im doing problems like using the slope intercept form to find the point slope to find standard, etc.

Question 700254: 20x+3y=20 and -20x+5y=60 using elimination
20x+3y=20 -20x+5(10)=60
-20x+5y=60 -20x+50= 60
----------- -50 -50
0+8y=80 --- ---
-- -- -20x-110
8 8 ---- ---
y=10 x=5.5
My question is, did I get the right answer, if not how did I mess up?

Question 700411: Would you pls help me to solve this:
Explain whether or not you agree or disagree with the following statement:
"Whenever you change the slope of a line, you change the intercepts of that line. It follows, then, that whenever you change intercepts of a line, you change the slope of that line."
Thanks.
