Answer:

The Answer is 12 - 15= 129

x2−15+15=129+15

x2=144

Tell whether the lines of the pair of equations are parallel, perpendicular, or neither.
tino4ka555 [31]
First Equation:

y= -\frac{3}{4} x+2

Second Equation can be written as:

y= \frac{3}{4}x+2

Slope of first equation is -3/4 and slope of second equation is 3/4. 
Slope of parallel lines must be equal, and slope of perpendicular lines are the negative reciprocal of each other. None of these conditions can be seen for given two equations.

So, the two lines are neither parallel nor perpendicular.
So correct option is C
