is 100
Answer:
(2,4)
Step-by-step explanation:
The range is the y values
y = x+5
Let y=7
7 =x+5
Subtract 5
7-5 x+5-5
2=x
Let y= 9
Subtract 5
9-5 x+5-5
4=x
The domain is (2,4)
5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5

Answer:
Step-by-step explanation:
Let s represent the son's age now. Then s+32 is the father's age. In 4 years, we have ...
5(s+4) = (s+32)+4
5s +20 = s +36 . . . . . eliminate parentheses
4s = 16 . . . . . . . . . . . . subtract s+20
s = 4
The son is now 4 years old; the father, 36.
_____
<em>Alternate solution</em>
In 4 years, the ratio of ages is ...
father : son = 5 : 1
The difference of their ages at that time is 5-1 = 4 "ratio units". Since the difference in ages is 32 years, each ratio unit must stand for 32/4 = 8 years. That is, the future age ratio is ...
father : son = 40 : 8
So, now (4 years earlier), the ages must be ...
father: 36; son: 4.
