Answer: 56 years
Step-by-step explanation:
Let Adam's age be , since the father is 3 times as old as him , then the father will be
.
Two years ago
Adam =
Father =
since Adam was 15 years old 2 years ago , this means that
add 2 to both sides
Therefore , Adam is presently 17 years old , then the father will be 3(17) years , which means that the father is presently 51 years old.
In 5 years time , the father will be 51 + 5 years old. That is , the father will be 56 years old in 5 years time
Answer:
The answer to your question is these lines are not perpendicular.
Step-by-step explanation:
Data
A (4, 2)
B (-1, 4)
slope = m = 4
Perpendicular lines mean that these lines cross and form an angle of 90°. Also, the slope of perpendicular lines is negative reciprocals.
Process
1.- Find the slope of the second line and compare it to the slope given.
slope =
Substitution
slope =
Simplification and result
slope =
-2/5 is not a negative reciprocal of 4, so these lines are not perpendicular.
