Since you are adding both negatives then it will just stay negative. For example -1-1=-2

Answer:

because adding a negative is the same thing as subtracting a positive, so the answer will be further negative than where it started.

also, you can tell because even if the 24 was positive, -38 is more negative than 24 is positive, so either way the answer will be negative.

Firstly , we will check continuity at x=1

we can use method

Suppose, f(x) is continuous at x=c

then it must satisfy

$\lim_{x \to c} f(x)=f(c)$

$\lim_{x \to 1} f(x)=f(1)$

firstly , we can find limit

$\lim_{x \to 1-} f(x)= \lim_{x \to 1-}(x+3)=1+3=4$

$\lim_{x \to 1+} f(x)= \lim_{x \to 1-}(3x+1)=3*1+1=4$

so, we get

$\lim_{x \to 1} f(x)= 4$

now, we can find f(1)

$f(1)=3*1+1=4$

so, we got

$\lim_{x \to 1} f(x)=f(1) =4$

so, this is continuous at x=1

ICE Princess25 [194]

The perpendicular slope would be the opposite of -8, so the perpendicular slope would be 1/8. For you to get this answer you have to change the sign from a negative to a positive, and flip the number to get 1/8.
