should i change this pfp or keep it the same??

ummidk l mean it's ur Choice if you like it then u can keep it

There's nothing wrong with your pfp. I would keep it. But its up to you if you want to change it or not.

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
