Wouldn’t that be a 1 in 3 chance, since their are 3 days?
X+6=y
Y^2-x^2=84
So substitute.
Y^2-x^2=84
(X+6)^2-x^2=84
X^2+12x+36-x^2=84
12x+36=84
12x=48
X=4
So then use this value to find y by substituting.
X+6=y
4+6=y
10=y
Answer:
Son = 14
Father = 42
Step-by-step explanation:
Let son age be x
Father's age is 3x and x + 28
3x = x + 28
2x = 28
x = 28/2 = 14
Father's age is x + 28 = 42
I'm pretty sure it's d. y=-3x
