Correct answer A) x+4y=8 , represents an equation of a line that has an x-intercept of 8 and a y-intercept of 2 .
<u>Step-by-step explanation:</u>
Here we have to identify Which of the following represents an equation of a line that has an x-intercept of 8 and a y-intercept of 2 .Let's find out:
A) x+4y=8
Let's check if line has an x-intercept of 8 i.e. at y=0 value of x is 8 :
⇒ 
⇒ 
⇒ 
Let's check if line has an y-intercept of 2 i.e. at x=0 value of y is 2 :
⇒ 
⇒ 
⇒ 
Hence , Correct option!
B) x=(-.25y+2)
Let's check if line has an x-intercept of 8 i.e. at y=0 value of x is 8 :
⇒ 
⇒ 
⇒ 
Incorrect option!
C) 4x+y=2
Let's check if line has an x-intercept of 8 i.e. at y=0 value of x is 8 :
⇒ 
⇒ 
⇒ 
Incorrect option!
D) y=-4x+8
Let's check if line has an x-intercept of 8 i.e. at y=0 value of x is 8 :
⇒ 
⇒ 
⇒ 
Incorrect option!

Answer:
one of them has a value that is ten times the value of the other one
Step-by-step explanation:
The most-significant 4 has a value of 40,000.
The least-significant 4 has a value of 4,000.
The most-significant 4 has a value that is 40,000/4,000 = 10 times that of the least-significant 4.

The basis of a place-value number system is that the value of a digit is multiplied by the value of the base when the digit is placed one more place to the left in the number. That is, the digit in the 5th place to the left of the decimal point will have a value that is 10 times the value of the same digit in the 4th place to the left of the decimal point.
