Step 1: (ab-9)(ab+8)
Step 2: ab x ab +8 x ab -9 x ab -9 x 8
Step 3: ab2 +8ab-9ab-72=
Step 4: ab2 -ab-72
solved!!! that how you would solve it everything will continue as normal
Answer:
It is TRUE for all Real numbers, i.e. [x] = ]x+1[ for all x∈R.
Step-by-step explanation:
Let's write given statement as [ x ] = ] x+1 [
where [ x ] step function means next integer greater than or equal to x,
and ] y [ means last integer less than or equal to y.
Let's take an example of x = 2.5
So [ 2.5 ] = 3.
and ] 2.5 + 1 [ = ] 3.5 [ = 3.
Similarly, we can take any example of Real numbers like 3.7, 4.2, 5.6, 8.9 etc.
It is TRUE for all Real numbers, i.e. [x] = ]x+1[ for all x∈R.
Answer:
x >-2
Step-by-step explanation:
-4(x-1)<12
Divide each side by -4, remembering to flip the inequality
-4/-4(x-1)<12/-4
x-1 > -3
Add 1 to each side
x-1+1 > -3+1
x >-2
open circle at -2
