Give your answer correct to 3 significant figures.
Total marks: 3

the correct answers i think are b. and d.

give me brainliest if it is correct!

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

her total is 2

  -3+5=2
