Answer:
x > -9/4
Step-by-step explanation:
Step 1 :
88
Simplify ——
5
Equation at the end of step 1 :
32 88
(0 - (—— • (2x - 1))) - —— < 0
10 5
Step 2 :
16
Simplify ——
5
Equation at the end of step 2 :
16 88
(0 - (—— • (2x - 1))) - —— < 0
5 5
Step 3 :
Equation at the end of step 3 :
16 • (2x - 1) 88
(0 - —————————————) - —— < 0
5 5
Step 4
-16 • (2x-1) - (88) -32x - 72
5 5
Step 5 :
Pulling out like terms :
5.1 Pull out like factors :
-32x - 72 = -8 • (4x + 9)
Equation at the end of step 5 :
-8 • (4x + 9)
————————————— < 0
5
Step 6 :
6.1 Multiply both sides by 5
6.2 Divide both sides by -8
6.3 Divide both sides by 4
x+(9/4) > 0
Answer:
AD= 15
AB=30
Step-by-step explanation:
We are given that the Point D bisect the line segment AB
Hence AD = DB
AD= 4x-1
BD=9x-21
Hence
4x-1=9x-21
adding 21 on both sides and subtracting 4x from both sides
4x-4x-1+21=9x-4x-21+21
-1+21=5x
5x=20
dividing both sides by x we get
x=4
Hence
AD = 4x-1
= 4(4)-1= 16-1=15
AD= 15
AB = 2 x AD
= 2 x 15
= 30
