2
step-by-step explanation:
x = 2
if sr parallel to ba then the sides bc and ac are in proportion, that is
= ← substitute values
= ( cross- multiply )
27x = 6(4x + 1)
27x = 24x + 6 ( subtract 24x from both sides )
3x = 6 ( divide both sides by 3 )
a) 0,0; 1,1; and 2,2
these have the exact same coordinates, thus they are the correct function.
