Answer:
The silver is now 50 years old and the gold coin is 18 years old
Step-by-step explanation:
first the silver was 32 years old , and it said it would be three times as old as the gold coin, to find the gold coin is to divide 32 and 3 together, that would be 10.6 but you can round the number up, you get 10 years.
you now can just get add 8 years to the 32 and 10
that would be 50 years old silver coin and 18 years for the gold coin.
Answer:
this is a liner polynomial
Step-by-step explanation:
Step-by-step explanation:
x intercept y=0
0 = 16x^2 - 60x -16
0 = 16x^2 + 4x - 64x - 16
0 = 4x (4x + 1) - 16 (4x + 1)
0 = (4x - 16) (4x + 1)
4x - 16 = 0 or 4x +1 = 0
4x = 16 or 4x = -1
x = 4 or x = -1/4
(4,0) and ( -1/4,0)
