Answer:
It means acidosis.
Step-by-step explanation:
When the pH level of the human blood is less than 7.35, the condition is known as acidosis.
When the pH level of the human blood is more than 7.45, the condition is known as alkalosis.
The organs which help to regulate the pH of human body is lungs.
Lungs remove the carbon di oxide through breathing or respiration.
Let b>a...
b=2(a+4)
b=2a+8 then we are told that:
b-a=11 using b found above in this equation gives you:
2a+8-a=11 combining like terms on left side
a+8=11 subtracting 8 from both sides
a=3
So the smaller number is 3.
...
since b=2a+8
b=14
check..
b=2(a+4)
14=2(3+4)
14=2(7)
14=14
and
b-a=11
14-3=11
11=11
Answer:
see explanation
Step-by-step explanation:
Given
x² - 2x - 4 = 0 ( add 4 to both sides )
x² - 2x = 4
To solve use the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 4 + 1
(x - 1)² = 5 ( take the square root of both sides )
x - 1 = ± 
( add 1 to both sides )
x = 1 ± , thus
x = 1 + or x = 1 -
