Answer:
B
Step-by-step explanation:
y - y1 = m (x - x1)
y1 = 3
x1 = 5
m(the slope)= -12
27. Replace b with 7, making 6 + 3(7). The 3 and parentheses of 7 hint multiplication, so you multiply to make 21, then add 6 relating back to PEMDAS to teach you the correct order to solve the problem.
a) From the left, the limit is 1, since
![\displaystyle\lim_{x\to1^-}f(x)=\lim_{x\to1}x=1](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Clim_%7Bx%5Cto1%5E-%7Df%28x%29%3D%5Clim_%7Bx%5Cto1%7Dx%3D1)
b) From the right, it's 2, since
![\displaystyle\lim_{x\to1^+}f(x)=\lim_{x\to1}2=2](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Clim_%7Bx%5Cto1%5E%2B%7Df%28x%29%3D%5Clim_%7Bx%5Cto1%7D2%3D2)
c) Also 2, same reasoning as in (b).
d) 1, since
![\displaystyle\lim_{x\to4^+}f(x)=\lim_{x\to4}(5-x)=1](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Clim_%7Bx%5Cto4%5E%2B%7Df%28x%29%3D%5Clim_%7Bx%5Cto4%7D%285-x%29%3D1)
e) No, neither two-sided limits exist because the respective one-sided limits do not agree.
Answer= 3/8 of a mile
