Answer:
Dan is 25 years old.
Step-by-step explanation:
1. Find out Dan's age from 8 years ago: 14 - 8 = 6
2. Find out how old Marge was: 6 ÷ 2 = 3
3. Add 8 years to Marge's age to find out how old she is now: 3 + 8 = 11
4. Add 14 years to Marge's age now to find out Dan's age now: 11 + 14 = 25
∴ Dan is 25 years old
{(a, 1), (b, 1), (c, 1)}, {(1, a), (2, a), (3, a)}, and {(a, a), (b, b), (c, c)}
**All functions are relations, but not ll relations are functions**
In a function, the x values CAN NOT repeat, only y-values can.
m = (y2 - y1)/(x2 - x1)
m =(220 - 100)/(3 - 0)
m = 120/3
m = 40
Hope this helps!
