Answer:
one to one function
Step-by-step explanation:
f(x)=6x+1 can only be a one to one function when x1=x2
Now,
f(x1)=f(x2)
or, 6x1 + 1 = 6x2 + 1
or, 6x1 = 6x2
or, x1 = x2
So f(x)= 6x + 1 is a one to one function
The answer is:
2((4^2)^-1)
= 2 * 16^-1
= 2 * 1/16
= 2/16
Answer = 1/8 (Decimal is 0.125)
Charles = Di multiplied by 3/5
Charles = Di minus 6
x multiplied by .6 = x - 6
15 multiplied by .6 = 15 - 6
Di = 15
Charles = 9
