Answer:
An irrational number produces an irrational when added to
Step by step explanation:
To find : What number produces an irrational when added to ?
Solution :
We know that,
It is a rational number as it is repeating.
So, If we add a rational number into a rational number it always gives you a rational number.
To produce an irrational number,
If we add an irrational number to a rational number it always gives you an irrational number.
For example :
An irrational number -
A rational number -
Adding these two number,
This number is non-terminating and non-repeating.
Therefore, An irrational number produces an irrational when added to
dome.
Answer:
O x = - 6 or x = 2
Step-by-step explanation:
x² + 4x - 4 - 8 = 0
x² + 4x - 12 = 0
x² + 6x - 2x - 12 = 0
x(x + 6)x - 2(x + 6) = 0
(x + 6) (x - 2) = 0
x + 6 = 0 or x - 2 = 0
x = - 6 or x = 2
Thus, x = - 6 or x = 2

1)first step
for the first inequation you need apply the following property, IXI < a
-a<x<a, them you must substitute 2x-3, of this form
-5<2x-3<5⇒ -5+3<2x-3+3<5+3⇒-2<2x<8⇒-2/2<2x/2<8/2⇒ -1<x<4,
the solution is
S1 =(-1,4)
2) For the second inequality apply the following property
IXI>a , x<-a or x >a , therefore
IX-2I>1 ⇒X-2 <-1 OR X-2> 1
X-2<-1⇒X-2+2<-1+2⇒ X< 1
OR
X-2>1⇒X>1+2⇒X>3
THE SOLUTION IS S2 = (-∞,1)∪(3,∞)
