Answer:

C. f(x) = x - 7 all over 4

Step-by-step explanation:

NB: Let f(x) = y

Exchange X and Y

Make y the subject

f(x) = 4x + 7

y = 4x + 7

x = 4y + 7

x - 7 = 4y

x - 7 all over 4 = 4 ÷ 4

y = x - 7 all over 4

How many parallel sides can a triangl have
katrin2010 [14]

Answer:

None.

Step-by-step explanation:

A triangle has <u>NO</u> parrallel lines. It cannot. Think of a triangle. IF it had a parralell line(s), it would not have 3 sides.

Otherwise, it wouldn't be a polygon which is part of the criteria for a triangle.

Hope this helps!
