Answer:
perpendicular
Step-by-step explanation:
Rewrite the equations
y = (-1/7)x - 3/7 -- L1
y = 7x + 25 -- L2
Slope of L1 x Slope of L2 = -1/7 x 7 = -1
As a result, the two lines are perpendicular
Z in (-oo:+oo)
Z/5+3 = -35 // + 35
Z/5+3+35 = 0
1/5*Z+38 = 0 // - 38
1/5*Z = -38 // : 1/5
Z = -38/1/5
Z = -190
Z = -190
I think that is the answer. . . . . . .

Hello,
The side of a triangle that is opposite an angle is the only side that does not form (touch) the angle.
Each angle of a triangle has two adjacent sides, the two angles that meet together to form that angle.
Hope this helps!
the answer is x1= -1 , x2= 5
