Required expression is x/9 - 7
Answer:
D
Step-by-step explanation:
Lets go case by case.
Given the roots, a factor will be part of the equation if for some of the roots the factor becomes null, i.e., equal to 0.
Is there any root that makes (x+3)=0? No, as it only becomes 0 for x = - 3 and -3 is not a root. So A NO!
Is there a root that makes (x-1)=0? No, as it only becomes 0 for x=1 and 1 is not a root. So B NO!
(x-4)=0 only for x=4, and as 4 is not a root, C NO!
The last, (x-3)=0 if x=3. As 3 is one of the roots, (x-3) is a factor of our equation!
D is the only correct option!
In 57,733 the values are:
5 is for tens
The first 7 is for ones
The second 7 is for tenths
The first 3 is for hundredths
The second 3 is for thousandths
Two set of digit in which one digit is ten times as great as the other are 3 and 3, as well as 7 and 7
It's because 0,03 is ten times as much as 0,003 and 7 is ten times as much as 0,7.
Step 1: move all terms to one side
7 + 2x^2 - 10x = 0
Step 2: Use the quadratic formula
X = 10 + 2(square root of 11). 10-2 _/—-11

Step 3: Simplify solutions
X= 5 + (square root of 11) 5 - (square root 11)

The answer is $160. You have to subtract 200 from 20%
