An equation used to solve a problem was (original amount)(0.30) = 48. Which situation(s) could be solved using this equation? Check all that apply.

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
