Answer:
Austin earned a higher score
Step-by-step explanation:
47/50 (Austin's score) = 94/100 (denominator is now 100) = 94% (converted to percentage) > 92% (Marty's score)
Hope this helps!
5 is the answer
when you multiply the numerator by the reciprocal of the denominator you get 5/81
The GCF is 
Explanation:
The GCF or greatest common factor is the factorization of two or more numbers to determine the greatest number that they have common.
The given terms are
and 
To determine the gcf of these two terms, let us find the greatest number that they have in common.
Comparing the powers of m from both the terms, we have,

Similarly, comparing the powers of n from both the terms, we have,

Also, comparing the powers of p from both the terms, we have,

Thus, the GCF of the terms
and
is 
9514 1404 393
Answer:
f(g(x)) = 8x^2 +11
Step-by-step explanation:
Put the argument where the variable is and simplify.
f(g(x)) = f(-4x^2 -9) = 2|-4x^2 -9 +3| -1 = 2|-4x^2 -6| -1
The expression -4x^2 -6 is never positive, so the absolute value function just negates it:
f(g(x)) = 2(4x^2 +6) -1 = 8x^2 +12 -1
f(g(x)) = 8x^2 +11
