Answer:
c
Step-by-step explanation:
y = x + 2 → (1)
2y = 5x + 4 ( divide through by 2 )
y = x + 2 → (2)
the 2 equations are the same and will have infinitely many solutions
Here's a rough graph haha
the graph has a factor of 4/1 (considered the "slope"), and the vertex is translated 2 units to the right (whatever is in the | lines | has the negative/positive flipped), and 6 units down.

Answer:
BC = 28 ft
Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
12BC = 340 ( divide both sides by 12 )
BC = =
= 28
