Question 74089: Thanks so much for all your help . After see the problem solve i try to work on them to make sure the are right . And i try to see hoe you all get the answer it is helping me to understand my probles .
So if some one can help me with these problems .
1) solve for x .collect xs on the LEFT side .The solution be presented with x first the correct inequality symbol ,then the number .
I have 10 of these to do .
but please help me with these .
1) 5(2x -1) <-8
2) X + 4 -8x-1≥3(x-2)


3) Name the coordinate described here
From the origin, the point is three places to the right and eight places down..

4) Find the midpoint between these points:
(-2, 7) and (-8,-5)


5) Please help me fill in the chart given this linear equation
Y=5x-4
I have to type all work below in the chart .Please I have 5 of these to do just give me an example on this one more thing where can I get the chart.



6) The linear equation y = 6x-5 graphs as a horizontal/ vertical/ diagonal line (choose the correct label and type it below)



Please tell me where I can get to do the midpoint the art for it.
Thanks .Enida

Question 74262: 1. Solve by elimination method
4x - y = -3
y - 3 = 4x

2. Solve by graphing method
x - y = 3
x + y = 1
3. Solve by addition method
1/5x + 2/3y = -8/5
3x - y = 9

Question 74263: I want to ask a queation please check to see if this is correct .If M (-7,-3) is the midpoint of segment PQ and the coordinates of Q and are(6,-3).fine the coordinates of Q .
Please see if my problem is correct .Thanks .
M(-7,-3)(6,-3)
7=3= -10 6/3=2
so if -10*2=20
so the P IS -20.-3
