I’m confused on what the question is
Answer:
no solution
Step-by-step explanation:
I'm pretty sure this is a trick question
the slope of the line is 0 and its y intercept is 1, so it will never hit y = 6
Answer: It will take 1.875 hours
Step-by-step explanation:
Given that time t required to do a job varies inversely as the number of people working.
we have it expressed as
t∝1/N
where t is time required to do a job
N is the number of people working.
Introducing our constant of proportionality, we have tht
t=k1/N
t=k/N
Now since it takes 5 hr for 3 cooks to prepare the food , K becomes
t=k/N
5=K/3
K=5X3=15
Given that there are 8 cooks, time required to prepare dinner will be
t=k/N
t=15/8
t=1.875 hours

4m - 2l = -10 ------- x
l = 3m ---------------- y
sub y into x
4m - 2(3m) = -10
4m - 6m = -10
-2m = -10
m = -10/-2
m = 5 years old
