Answer:
1-
Step-by-step explanation:
because 1 was removed from it
Points m and n
Are the answer
So just add 2 1/2 = 2.5and 1 1/4= 1.25 and that will equal, 3.75 cups in other words that will equal 3 3/4.cups of sugar total.
Answer: Solution: (12, 3)
Step-by-step explanation:
2x - 4y = 12
3x + 4y = 48
Add both equations
5x = 60
Divide both sides by 5
x = 12
We can use the value of x to find y
3x + 4y = 48
3 (12) + 4y = 48
36 + 4y = 48
Subtract 36 from both sides
4y = 12
Divide both sides by 4
y = 3
Solution: (12, 3)
We have
and
so the equation is indeed exact. So we want to find a function 
such that
Integrating both sides of the first equation wrt 
gives
Differentiating both sides wrt 
gives
So we have
or
