Identify the solution to the following inequality: -1/2 (x+3) > x - 3
2 answers:
Answer:
A
Step-by-step explanation:
- 
(x + 3) > x - 3 ( multiply both sides by 2 to clear the fraction )
- (x + 3) > 2x - 6 ← distribute parenthesis on left side by - 1
- x - 3 > 2x - 6 ( subtract 2x from both sides )
- 3x - 3 > - 6 ( add 3 to both sides )
- 3x > - 3
divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity
x < 1
Answer:
A. x<1
Step-by-step explanation:
-1/2 (x+3) > x - 3
(-1/2)x-3/2>x-3
Multiply both sides by 2:
-x-3>2x-6
add both sides by 3:
-x-3+3>2x-6+3
-x>2x-3
minus both sides by 2x
-x-2x>2x-2x-3
-3x>-3
x<1

Answer:
32 005
Step-by-step explanation:
use this formula
Tn = a +(n-1)d
A= 1/2Bh
A= 1/2 (10.2 x 8)
A= 1/2 (81.6)
A=81.6 / 2
A= 40.8
Answer:
13.6
Step-by-step explanation:
5 divided into 68 is basically the same thing as 68 divided by 5.
68/5 is equal to 13.6
The common factor is 2 so: 2(4x+3) is the answer
Step-by-step explanation:
3cos2x +sinx=1
3(1-2sin²x)+sinx=1
3-6sin²x+sinx=1
sinx(-6sinx+1)=1
either
sinx=1
sinx=sin(90)
:.x=90
or
-6sinx+1=1
-6sinx=1-1
sinx=0/-6
sinx=sin0,sin180
:.x=0,180and90
