Solve the given differential equation by using an appropriate substitution. the de is of the form dy dx = f(ax + by + c), which is given in (5) of section 2.5. dy dx = 4 + y − 4x + 5

No idea what the cited section's method is, but this ODE is linear:

Multiply both sides by so that the left side can be condensed as the derivative of a product:

Integrating both sides gives

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
