The one with the fraction in the parenthasees
remember
F=P(r)^t
in decay, r<1
in growth, r>1
and r is positive so we don't have wierd fliping values
answer would be f(x)=4(0.25)^x
2nd one is answer
Y=-3x+23
distribute -3, get y alone (add 2 to both sides)
Answer:
option D is the correct answer
A. Multiplied by 2 for the first then for the second multiply by three.
Explanation: the equations already have opposite signs for y so reversing the signs would be counterproductive. (Eliminates B and D) and the easiest way is to get the numbers before the Y variable to be the same. The top by 2 and bottom by 3 would do that, leaving only A.
