Answer:
x = -2
Step-by-step explanation:
3(5x + 2) = 2(3x - 6)
<em>Expand the brackets. </em>
15x + 6 = 6x - 12
<em>Isolate the unknown variable x. </em>
15x - 6x = -12 - 6
<em>Evaluate. </em>
9x = -18
<em>Find x. </em>
x = -18 ÷ 9
x = -2
For the equation of the line expressed as Ax + By + C = 0, the value of the slope (m) is calculated by -A / B. For perpendicular lines, the slope of one should be the negative reciprocal of the other. From the choices given, the lines that are perpendicular is Option A.
