Answer:
mary=10 jack=15
Step-by-step explanation:
After 4 years Mary (x+4), Jack's age (x+5) + 4.
sum of the ages after 4 years :(x+4) + (x+5) +4=33
Simplifying the equation:
2x+13 = 33 ----->> 2x=20----->>>>x = 10 Mary's age
10 + 5 = 15 which is Jack's age.
Y=4x+2 on (0,3) so start at the point (0,3) then go up 2 and there is your answer!
Answer : = 55/9
step by step explanation : Divide both sides of the equation by the same term
55=9x
55/9= 9x/9
Answer:
Step-by-step explanation:
The integer points which fall in the common region bounded by the lines are
Since, one of the points is 
we round it to 
If we round up then the point will be 
which does not fall in the bounded region.
Also 
and 
no negative values are considered.
Applying in the values in the LP problem 
So, the LP problem is maximum at point .
