X = one of the box
x + 4 = second both
38 = total weight(pounds)
Now combine them
x + x + 4 = 38
2x = 34, x = 17
17 + 4 = 21 (second box)
One box weights 17 pounds and the other weighs 21 pounds
Answer:here is something to keep in mind.
when there is a downward slope, the slope will ALWAYS have a negative slope. even if it is above the x-axis. negative slopes will tend to go from positive y-axis to negative y-axis
so personally would have to go with -4
because the x-axis is by 4 each time. and this slope is going downward.
your answer will be D
Well 1.75 as a mixed number would be 1 75/100.
the answer would be for a improper faction would 175/100.
hope that helped
Answer:
Step-by-step explanation:
Differentiating, you get ...
... x·dy +y·dx +dx +dy = 2x·dx +2y·dy
Collecting terms gives ...
... dy(x +1 -2y) = dx(2x -y -1)
... dy/dx = -(2x -y -1)/(2y -x -1)
Answer:
the second one
