Which statements are true according to the order of operations? choose exactly two answers that are correct.
a. 32+8÷4=40÷4=10
b. 4+12÷2=4+6=10
c. (20–5)•3=15•3=45
d. 12+(6÷3)=18÷3=6

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

you need to give us more information since we can't answer
