Which answer is correct?
Ol won $
OI lost $ 65
Answer:
B. 
and 
Step-by-step explanation:
The expression given is:
Like terms are terms in which their variables and the power of the variables (exponents) are the same.
While it is not necessary that the coefficient of the variables are the same, the power of the variables must be the same.
In that case, the like terms in the expression given are and .
Note: The question says but the option has 
.
In case its actually instead of 
, then, is also a like term and the answer will be D.
Answer:
25/28
Step-by-step explanation:
make the denominator to 28 by doing 4 x 7
3 /4 x 7 = 21/28
1/ 7 x 4 = 4/28
21/28 + 4/28 = 25/28
These are just sketches, you should polish them yourself. In analogy to relations, I will write aFb to mean the statement f(a) = b.
(a) aFa, so f(a) = a. This is the definition of the identity function.
(b) aFb => bFa, so f(a) = b and f(b) = a. Therefore f(f(a)) = a by substitution, and hence f^2 is the identity function.
(c) aFb and bFc => aFc. So f(f(a)) = c, and f(a) = c. Thus f(c) = c, which is the identity. Make sure you sort out the im(F) stuff when you clean this up.
