7 0

Answer:

See below

Step-by-s.ep explanation:

6. Let the 3 integers be k-2, k and k+2.

So k(k+2)-k(k-2) = 28

k^2 + 2k - k^2 + 2k = 28

4k = 28

k = 7.

So the 3 integers are 5, 7 and 9.

Which function is the inverse of y= -3x + 6/7
Alenkasestr [34]

Answer:

y=-1/3x+2/7

Step-by-step explanation:

y=-3x+6/7

x=-3y+6/7

-3y=x-6/7

y=-1/3x+(6/7)/3

y=-1/3x+(6/7)(1/3)

y=-1/3x+6/21

y=-1/3x+2/7

Consider this function. f(x)-3x+3. Which graph represents the inverse of function f?
Kamila [148]

9514 1404 393

Answer:

  graph Y

Step-by-step explanation:

The inverse function can be found by solving ...

  x = f(y)

  x = -3y +3

  x -3 = -3y . . . . . subtract 3; next, divide by -3

  y = -1/3x +1 . . . . . matches graph Y

_____

<em>Additional comment</em>

Writing the original equation in standard form can help you see its intercepts.

  3x +y = 3

  3x = 3   ⇒   x = 1 . . . . x-intercept (at y=0)

  y = 3   . . . . y-intercept (at x=0)

The inverse function has the x- and y-intercepts swapped, so you're looking for a line through (0, 1) and (3, 0). The lower left graph (Y) is that graph.
