Answer:
yes
Step-by-step explanation:
repeating decimal. when a fraction is changed to a decimal and the remainder is not zero, a digit or a block of digits will eventually start to repeat. terminating or repeating decimal. since a rational number is a number that can be written as a fraction, every rational number can be expressed as either.
Answer:
yes they are inverserve of each other
Step-by-step explanation:
f(x) = y just for say
y=3x+9
switch the x and y value and solve for y
x=3y+9
x-9=3y
(x-9)/3 = y
inverserve of f(x) is g(X)
and now g(x) = y
y= (x-9)/3
switch x and y and solve for y
x=(y-9)/3
3x= y-9
3x+ 9 = y
inverserve of g(x) is f(X)
This is written as 340 - 130 or 340 + (-130); I don't know if you need the answer or not but it is equal to 210!
