-5(3-4x)=-6+20x-9
solve for x

the answer to the expression is 83

answer: 12

step-by-step explanation:

because yes

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

step-by-step explanation:

no solution.
