At the grocery store, we bought 2 ½ pounds of cabbage, 5 pounds of apples, 20 pounds of potatoes, and 20 pounds of carrots. How many vegetables did they buy?

42 1/2

Step-by-step explanation:

2 1/2 + 20 + 20

So 20+20= 40 +2 and a half so the answer is 42 1/2

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:

option c
