Let us perform the operation and express your answer as a single fraction
Therefore, we conclude that:
Answer:
A.) (-1,-6) and (-3,-2)
Step-by-step explanation:
The given line segment has coordinates
(-1,6) and (-3,2)
The mapping for a reflection in the x-axis is
This implies that;
and
The correct choice is A.
Let ‘s’ be the son’s age 12 years ago.
Let ‘f’ be the father’s current age.
4 years ago, the son was:
s-4
So, his father is currently:
3(s-4)
=
3s-12
Therefore:
f = 3s-12
In twelve years, the son will be:
s+12
And the father will be:
f+12
This can also be written as:
3s-12+12 as the fathers younger age would be f = 3s+12
=
3s
So, we know that s+12 is half the fathers current age, meaning the father is currently 2(s+12) which is equivalent to 2s+24. Also, we know that the father is currently 3 times the sons age 12 years ago, so 3s (proven by the calculations we made above). Therefore, 2s+24=3s which means 24=s. We can then substitute this, and we will receive 24+12 = 36
Son’s current age: 36
We then substitute the son’s age 12 years ago into 2s+24 to give us the father’s age.
2(24)+24 = 72
Father’s current age: 72
The answer is 9 Dollars per hour because 36 divided by 9 is 4 and 9 times 9 is 81.
