Answer: The change in the value of x would be : [tex]\Delta x=4.5 [/tex] .
Step-by-step explanation:
We know that if y represents the value of some varying quantity, then as the value of y varies from p to q.
The change in the value of y is given by :-
[tex]\Delta y=q-p[/tex] [Next value - previous value]
Given : x represents the value of some varying quantity.
So , As the value of x varies from 3.5 to 8.
The change in the value of x is given by :-
[tex]\Delta x=8-3.5=4.5 [/tex]
Hence, the change in the value of x would be : [tex]\Delta x=4.5 [/tex]
