Ok to figure out if one is an inverse function, you plug in y for x and substitute f(x) with x and solve for y.
We only have to do this for 1 of the functions so we will take f(x)
x = 5y +1/y
I’m not sure you can solve for y here therefore g(x) is not an inverse function of f(x)
Answer:
Logically it would be 1/8 chance but since I don't know what color the all are, It's hard to tell
Step-by-step explanation:
Answer:
can also be expressed as a ratio of two integers.
Step-by-step explanation:
Assume x and y are rational number, then x and y can be written as:
, where a and b are integers and b≠0
, where c and d are integers and d≠0
Then,
= 
= 
Since the set of integers are closed under multiplication, a*d is also an integer. Similarly b*c is also an integer.
can be expressed as a proportion of two integers, provided that y≠0. From this we can conclude that is a rational number, which concludes that the set of rational numbers are closed under division.
1. (5+23)+65 = (5+65)+23 = 70+23 = 93 (D)
2. -(4x-7) = -4X+7 (C)
3. 2(6X+9) = 12X+18 (B)
4. 5(X-3) = 35
X-3 = 35/5
X-3 = 7
SO X= 7+3 = 10
THEN NO
9 IS NOT A SOLUTION
