Solve for A.
R = X(A + B)

Divide each term in x(A+B)=R x ( A + B ) = R by A+B A + B .

Step-by-step explanation:

Rewrite the equation as x(A+B)=R x ( A + B ) = R . Divide each term by A+B and simplify

c

step-by-step explanation:

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
