Question

I need help with inequalities

Answer 1

Match the terms with the definitions.
A. x-1 > 5
B. 2x ≤ 6
C. x - 7 > -4
D. -2x < 6
E. 4 < -4x
F. -2x + 3 < -7
G. 5x + 1 ≥11
H. 3(x+4) > 8x -6
I. -3x + 4 < -x + 2
J. -2(x-4) > 5 - (x+2)

1.)x < 18/5, open dot at 18/5 and shaded to the left
2.)x > 6, open dot at 6 and shaded to the right
3.)x > -3, open dot at -3 and shaded to the right
4.)x<5, open dot at 5 and shaded to the left
5.)x ≤ 3, closed dot at 3 and shaded to the left
6.)x< -1, open dot at -1 and shaded to the left
7.)x > 3, open dot at 3 and shaded to the right
8.)x > 1, open dot at 1 and shaded to the right
9.) x > 5, open dot at 5 and shaded to the right
10.) x ≥ 2, closed dot at 2 and shaded to the right.

Please help...Its one of my last quizes for the night :)

Answer 2

lol. i know!

Answer 3

im so stuck thought, this is horrible

Answer 4

"/

Answer 5

well Here we go

Answer 6

A. x-1 > 5 -----------> x > 5 + 1 x > 6

B. 2x ≤ 6 -----------> x ≤ 6/2 x ≤ 3

Answer 7

C. x - 7 > -4 ----------> x > -4 + 7 x > 3

D. -2x < 6 ------------> -x < 6/2 x > -3

Answer 8

E. 4 < -4x ------------> 4/4 < -x -1 > x x < -1
F. -2x + 3 < -7 --------> -2x < -7 -3 -2x < -10
-x < -10/2 x > 5

Answer 9

G. 5x + 1 ≥11 -----> 5x ≥11 - 1 5x ≥10 x ≥ 2
H. 3(x+4) > 8x -6 ------> 3x + 12 > 8x - 6
12 + 6 > 8x - 3x
18 > 5x 18/5 > x x< 18/5

Answer 10

I. -3x + 4 < -x + 2 ----> 4 -2 < 3x - x 2 < 2x x > 1
J. -2(x-4) > 5 - (x+2) ----> -2x + 8 > 5 - x -2
8 - 5 + 2 > 2x -x
5 > x x < 5
