Call (F) the age of the father and (J) the age of Julio
The F & J are related in this way: F=4J
Now you have a restriction in the form of inequality: The sum of both ages has to be greater or equal than 55.
Algebraically that is: F + J ≥ 55
You can substitute F with 4J to find the solution for J:
4J + J ≥ 55
5J ≥ 55
Now divide both sides by 5
5J/5 ≥ 55/5
J ≥ 11
That Imposes a lower boundary for the value of J of 11, meaning that the youngest age of Julio can be 11

Answer:
Step-by-step explanation:
two points on the line are (-3,-2) and (5,4)
slope=(4+2)/(5+3)=6/8=3/4
eq. of line is
y+2=3/4 (x+3)
4y+8=3x+9
4y=3x+1
y=3/4 x+1/4
Answer:
the following are all equal
3/5 (x1)
6/10 (x2)
9/15 (x3)
12/20 (x4)
