Find the slope of the function f ( x ) = 3 - 2 x , by the definition of limit.

musickatia [10]

Answer:

the slope is -2 $\lim_{n \to \0}( f(x+h)-F(x)) /h \\\\ \lim_{n \to \0} (3-2(x+h)-(3-2x))/h\\ f(x+h)= 3-2(x+h) \\f(x)=3-2x\\ \\\lim_{n \to \0} (3-2x-2h-3+2x)/h\\\\ \lim_{n \to \0} -2h/h\\ \\ \lim_{n \to \0} -2\\=-2\\\\In all limits, you have to put n goes to 0 (zero)$

Zinaida [17]

Given :

⊕ Blake fell asleep after they had travelled 702 miles

⊕ Total length of the trip : 900 miles

$\implies:$ Distance travelled by Blake's family after he fell asleep : (900 - 702)

$\implies:$ Distance travelled by Blake's family after he fell asleep : 198 miles

% of total trip Blake's family travelled after he fell asleep :

$\implies \ \ \dfrac{\textsf{Distance travelled by Blake's family after he fell asleep}}{\textsf{Total Length of the Trip}} \ \times \sf{100}$

$\sf{\implies \ \ \dfrac{198}{900} \ \times 100}$

$\sf{\implies \ \ \dfrac{198}{9}}$

$\sf{\implies \ \ 22\%}$
