Answer:
x = 7
Step-by-step explanation:
For the two lines to be perpendicular, the sum of the two equations has to equal 90 degrees:
2x + 4 + 11x - 5 = 90
Combine like terms:
13x - 1 = 90
Add 1 to both sides to isolate the 13x:
13x = 91
Divide both sides by 13 to isolate x:
x = 7
The value of x is 7.
Hope this helps :)
