You can eliminate fractions by multiplying the whole thing by 7.
... -x +28 ≥ 21x
Now, add x to get all x-terms on the right. Then, divide by the coefficient of x.
... 28 ≥ 22x
... 28/22 ≥ x
This fraction can be reduced, so we have ...
... A. x ≤ 14/11
I guess the original function was
y = 5x (1)
y+Δy =5(x+Δx) (2)
(2) - (1) =
Δy = 5Δx
Δx →0, Δy/Δx →5
