Answer:

a

Step-by-step explanation:

because thats the point of intersection meaning for 4 hours it costs 70$ for both

the slope for company a is y = 10x + 30

the slope for company b is y = 5x + 50

and if you plug in 4 for x in both

10(4) + 30 = 40 +30 = 70

5(4) + 50 = 20 + 50 = 70

Find the sum. <br> 5k/k^2-2k+1 <br><br> + <br><br> 2/k^2+k-2
Alchen [17]
\dfrac{5k}{\underbrace{k^2-2k+1}_{(a-b)^2=a^2-2ab+b^2}}+\dfrac{2}{k^2+k-2}=\dfrac{5k}{(k-1)^2}+\dfrac{2}{k^2+2k-k-2}\\\\=\dfrac{5k}{(k-1)^2}+\dfrac{2}{k(k+2)-1(k+2)}=\dfrac{5k}{(k-1)^2}+\dfrac{2}{(k+2)(k-1)}\\\\=\dfrac{5k(k+2)}{(k-1)^2(k+2)}+\dfrac{2(k-1)}{(k-1)^2(k+2)}=\dfrac{5k^2+10k+2k-2}{(k-1)^2(k+2)}
=\dfrac{5k^2+12k-2}{(k-1)^2(k+2)}=\dfrac{5k^2+12k-2}{(k^2-2k+1)(k+2)}\\\\=\dfrac{5k^2+12k-2}{k^3+2k^2-2k^2-4k+k+2}=\dfrac{5k^2+12k-2}{k^3-3k+2}

Describe the continuity of the graphed function. Select all that apply.
victus00 [196]

Using continuity concepts, it is found that the correct options are:

  • The function is continuous at x = -4.
  • The function has an infinite discontinuity at x = -1.

-----------------------------

A function f(x) is continuous at x = a if:

\lim_{x \rightarrow a^{-}} f(x) = \lim_{x \rightarrow a^{+}} f(x) = f(a)

-----------------------------

  • At x = -4, there are no changes in the definition of the function, thus, it is continuous.
  • At x = -1, we have that:

\lim_{x \rightarrow -1^-} f(x) = 0

\lim_{x \rightarrow -1^+} f(x) = f(1) = 1

  • A different definition depending on the which side of -1 the function is, thus, it is a jump discontinuity.
