Answer:
z ≥ -8 - (-5)
Step-by-step explanation:
Answer:
none
Step-by-step explanation:
he works for one direction.
Answer:
14 > -2 (2z + 3)
First you need to distribute the -2 inside the parentheses.
14 > -2(2z) + -2(3)
14 > -4z - 6 -Add 6 to both sides of the equation
14 + 6 > -4z - 6 + 6
20 > -4z -Now divide by -4 on both sides
20 / -4 > -4z / -4
-5 > z
However, when you divide by a negative number, you MUST flip the sign.
So, the answer is:
-5 < z

1+1+1 is 3. And you have 1/3+1/3+1/3=3/3=1. So you end up with 3+1=4. So yes
Answer:
A. 12x² + 15xy + 18x
B. - 12x² + 18xy + 24x
C. 10x² - 31x - 14
D. x² - 36
3a. x = 8
3b. x = 3
Step-by-step explanation:
A. 3x ( 4x + 5y +6 ) C. ( 2x - 7 ) ( 5x + 2 )
12x² + 15xy + 18x 10x² + 4x - 35x - 14
10x² - 31x - 14
B. 6x ( 3y - 2x + 4 )
18xy - 12x² + 24x D. ( x + 6 ) ( x - 6 )
-12x² + 18xy + 24x x² - 6x + 6x - 36
x² - 36
3a. 5/4x + 2 = 12 3b. 7/3x - 2 = 5/3x
5/4x = 12 - 2 -2 = 5/3x - 7/3x
5/4x = 10 -2 = - 2/3x
x = 10 · 4/5 -2/3x = -2
x = 8 x = 3
