The graph below shows two linear functions.
Which explanation could be used to verify whether the
functions are inverses?
Neither of the lines is parallel to the line y=x, therefore,
the functions are inverses of each other,
Neither of the lines is parallel to the line y = x therefore,
the functions are not inverses of each other.
The point of intersection of the two functions is not on
the line y=x, therefore, the functions are inverses of
each other.
The point of intersection of the two functions is not on
the line y = x, therefore, the functions are not inverses of
each other

The point of intersection of the two functions is not on

the line y = x, therefore, the functions are not inverses of

each other

Step-by-step explanation:

For A and B, it doesn't matter whether they are parallel to the line y=x; so we can take those two out of the equation. You can check to see whether they actually intersect by take a point from the orange graph and flipping the x and y values ie: the point (0,3) --> (3,0); and if that point is included on the other graph (I would do a couple to make sure) you know that they are the inverses of each other- in this case the blue one is not the inverse of the orange. You could also draw the line y=x through the graph and see whether the points are an equal distance from the line on either side. (I'm not sure whether you've done either way before but that's why I'm giving you a couple). Also, you could literally just check the point of intersection and make sure that it is on line. Hope that helps!

hi, i am not sure about this one but i think its d,

hope this !

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
