Answer:5
Step-by-step explanation:
M=-1/2 because you do y1-y2 over x1-x2 and end up with 2/-4 but simplified is -1/2
Answer: $14.85
Step-by-step explanation:
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
The answer will be 9 1/12 because if you add them up you get 11/12. So the mixed number would be 9 1/12
