Solve :
20-9x=11
4(2x+1)=8
5(2x+5)=-15
3(8x+1)=-21
Answers
-9x=11-20
-9x= -9
x= -9/(-9)
x=1
4(2x+1)=8
2x+1=8/4
2x+1=2
2x=2-1
2x=1
x=1/2
x=0.5
5(2x+5)=-15
2x+5= -15/5
2x+5= -3
2x= -3-5
2x= -8
x= -8/2
x=-4
3(8x+1)=-21
8x+1= -21/3
8x+1= -7
8x= -7-1
8x =-8
x= -8/8
x= -1

Answer:
Step-by-step explanation:
First we need to find the point that the perpendicular line goes through on this line segment. The problem says it's a perpendicular bisector, which means it goes through the middle of the line, which means the point it goes through is halfway between (4, 4) and (-8, 8). This point would be (-2, 6).
Next, we need to find the slope of the perpendicular line. We know that if the slope of the line segment we're given is , then the slope of the line perpendicular to this line segment is
.
The slope of the line segment can be found by the following:
This means that the slope of the perpendicular line is 3.
The equation of a line is , were
is the slope and
is the Y-intercept.
We know the slope, we so we just need to determine the Y-intercept. To do so, we can plug in a point that we know the line goes through, (-2, 6), and solve for :
Finally, the equation of the line is

Answer:
x > 3
Step-by-step explanation:
8x - 6 > 12 + 2x....,just move the values with variable x to one side and those without to the other side
; 8x - 2x > 12 + 6
; 6x > 18...., then divide by 6,both sides of the inequality
; x > 3
