Please help. What is the equation of the line that has a slope of 3 and goes through the point (-3,-5)?

fiasKO [112]

Answer:

y = 3x + 4

Step-by-step explanation:

We can use the equation y = mx + b to find the equation:

Plug in the slope and the point into the equation, and we can find b:

-5 = 3(-3) + b

-5 = -9 + b

4 = b

Now, we can plug in the slope and y-intercept into the equation:

y = 3x + 4 will be our equation

Find the limit of (sqrt(x+5)-4)/(x-11) as x approaches 11

Zanzabum

$\lim\limits_{x\to11}\dfrac{\sqrt{x+5}-4}{x-11}=\lim\limits_{x\to11}\dfrac{(\sqrt{x+5}-4)(\sqrt{x+5}+4)}{(x-11)(\sqrt{x+5}+4)}\\\\=\lim\limits_{x\to11}\dfrac{(\sqrt{x+5})^2-4^2}{(x-11)(\sqrt{x+5}+4)}=\lim\limits_{x\to11}\dfrac{x+5-16}{(x-11)(\sqrt{x+5}+4)}\\\\=\lim\limits_{x\to11}\dfrac{x-11}{(x-11)(\sqrt{x+5}+4)}=\lim\limits_{x\to11}\dfrac{1}{\sqrt{x+5}+4}=\dfrac{1}{\sqrt{11+5}+4}\\\\=\dfrac{1}{\sqrt{16}+4}=\dfrac{1}{4+4}=\dfrac{1}{8}\\\\Answer:\ d.\ \dfrac{1}{8}$
