Answer:
The seccond one B
Step-by-step explanation:
g (f (4)) = -24
Explanation:
g(n) = 4n
f (n) = -2n + 2
f(4) means n = 4
f(4) = -2(4) + 2
f(4) = -8 + 2
f(4) = -6
g (f (4)) means n = f(4) = -6
g(-6) = 4(-6)
g(-6) = -24
g (f (4)) = g(-6)
Therefore, g (f (4)) = -24
(40 - x) represents A. the number of undamaged cards
Step-by-step explanation:
Step 1; Maria has a total of 40 cards out of which x number of cards are damaged so 40 - x cards are undamaged. The value of an undamaged card is 5 dollars whereas every damaged card has a value of 3 dollars.
Step 2; We need to determine what each term in equation 5(40−x)+3x represents. The equation will give us how much total value Maria's card collection has.
The first term 5 (40 - x) signifies the total value of the undamaged cards in the deck where (40 - x) equals the total number of undamaged cards.
The second term represents the total value of the undamaged cards.
So the second factor of the first term i.e (40 - x) represents the amount of undamaged cards in her collection.
X + 8 = -x + 7
it can be set up like this :
y = x + 8
y = -x + 7
