Step-by-step explanation:

Total weight of all 3 books = 2 7/16 + 1 7/8 + 1/2

Finding the common denominator,

2 7/16 = 39/16

1 7/8 = 15/8 = 30/16

1/2 = 8/16

Total = 39/16 + 30/16 + 8/16

= 77/16 = 4 13/16 pounds = 5 pounds

Total is less than 6 pounds. So, Gina can ship all 3 books.

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
