20 x cents already given in question
converting 5 y dollars into cents (1 dollar=100 cents, 5 dollars =500 cents)
5 y dollars =500 y cents
20 x cents+500 y cents
20 x + 500 y cents
It is 12 (explanation: unit rate is per unit so 16/16 mile or 1 mile = x minutes so if you multiple 1/16 by sixteen and do the same on the other side (3/4 times 16), you get 20 (hope this helps!)
Answer:
-x^2 +x
Step-by-step explanation:
f(x) = 1-x^2
g(x) = 1 - x
f(x) - g(x) = 1-x^2 - (1 - x )
Distribute the minus sign
= 1-x^2 -1 +x
Combine like terms
= -x^2 +x
