Answer:
A= Rate of change is y=4x, this is because it is set up as y/x and for the graph B= y=3x. Function A is greater in change than Function B because if you substitute x for 1, A would be 4 and B would be 3.
Step-by-step explanation:
Answer:
5m - 4n
5(5) - 4(3) ( As m= 5 and n= 3)
25 - 12
= 13
So it cooks for 2 hrs and 20 minutes......and it has to be done by 1 pm.
so from 1 p.m. - 2 hrs = 11 a.m........- 20 minutes = 10:40 a.m
start cooking at 10:40 a.m. and it will be done by 1 p.m
