Step-by-step explanation:

x = 14

Step-by-step explanation:

Since the triangle is isosceles, then the legs are congruent, both 4x - 5

Sum the lengths of the sides and equate to 116

4x - 5 + 4x - 5 + x = 116 , that is

9x - 10 = 116 ( add 10 to both sides )

9x = 126 ( divide both sides by 9 )

x = 14

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
