Explain the mistake 3/6 + 1/3 = 4/9

The answer should be 5/6

Step-by-step explanation:

The problem just adds both the numerator and the denominator which is something you can't do. You have to find the least common denominator, which in this case is 6, and change the numerator as the denominators have been changed. So 1/3 becomes 2/6. 3/6 + 2/6 = 5/6

the first one, all those points on the line just make a strait line.

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
