4.) 1/2(3x-1) - 1/4(2x+6) > x+1 1.5x - 0.5 - 0.5x - 1.5 > x+1 1.5x - 0.5x - 1.5 - 0.5 >x+1 x+2 > x+1 x > x-1 0 > -1

YAY I GOT IT TO WORK! so excited for algebra tomorrow! -Lucy Hazel

5 [3-2x] = x + 4 - 4 - 4 5 [3-2x] – 4 = x 15-10x-4 = x 11 – 10x = x +10x +10x 11 = 11x /11 /11
 * 1

X = 1

heyy i think i got this to work! --Paige McDermott

It works for me! Hey Algerbra 2 kids! -Megan Cook

Hey. . . it works!!!! --Shasta!

hey there-elizabeth geyer

YAY FINALLLYYYYYYY- james ||
 * LLAMAS!!!!!!!!!
 * D

-seb this is kahlil. HELLO || 3. 3x +11 > 1 - 11 -11 3x> - 10 /3 /3
 * 3x + 11| > 1

x > -10/3

-Nia

Okay I don't know if i'm doing this right? I hope so!! See everyone tmmrw! - Olivia

5. Shasta y=mx+b standard equation form y=(-3/2)x+b perpendicular slope to 2/3 4=(-3/2)(-3)+b plug in given point 4=(9/2)+b simplify 4=4.5+b change to decimals b=-.5 subtract 4.5 from both sides y=(-3/2)x-0.5 put it all together -Shasta

1. 5|3-2x| = x + 4 15 - 10x = x + 4 11 = 11x x = 1 - Megan Cook

3. |3x + 11| > 1 3x + 11 > 1 3x > -10 x > -10/3

-3x -11 < 1 -3x < 12 x = < -4 Answer { -10/3, -4} -Megan Cook

Hi guys! - Britnae

hi from Joshua

2.I2x-1I <_ 7 -2x+1_< 7 -2x_<6 x>_-3 2x - 1 _< 7 2x _< 8 x _< 4 x_ _ -3

heyy=)

its tania I FINALLY GOT IT =)

- elizabeth geyer the _< and the_> are greater than or equal =to and less than or equal to=

hiii =) its tania

okkk so... i dont know how to put a picture on here.. but i DID graph it =) 6) 4 if x<-3 --> (-3,4) open circle, (-4,4) (-5,4)........ ( horizonatal line) y= x+2 if -3 <_ x < 1--> x>_-3 and x<1 -> (-3, -1) (1, 3) open circle ( line segment) -2x+1 if x >_ 1 >(1, -1), (2, -3)

5) m=-3/2 y= -3/2x + b (-3, 4) 4= -3/2 (-3) +b 4=9/2 + b -1/2 = b

y= -3/2x - 1/2 2(3/2x + y) = (-1/2)2 3x + 2y = -1 STANDARD FORM
