Can someone help me with my math homework? It is due today and I don’t understand. Could you also explain how you got the answer
Assoli18 [71]

Answers

(1) a = 16 , (2) x =4 , (3) x = 0 ,(4) n =-20 , (5) r = 20 and (6) x = -11

Step-by-step explanation:

(1) 6 = a/4 + 2

4 = a/4 (It is because when you bring +2 over to the left it will become 6 -2)

a = 16 (it is because of the fraction, so when you bring the divisor over it becomes x 4)

The following questions same as qns 1 too

(2) -6 + x/4 = -5

x/4 = 1

x = 4

(3) 9x -7 = -7

9x = 0

x = 0

(4) 0 = 4 + n/5

-4 = n/5

n = -20

(5) -4 = r/20 -5

1 = r/20

20 = r

(6) -1 = 5 + x/6

-6 = 5 + x

-11 = x

Answer:

Step-by-step explanation:

Hello, please consider the following.

\displaystyle f'(0)=\lim_{x\rightarrow0} {\dfrac{f(x)-f(0)}{x-0}}\\\\=\lim_{x\rightarrow0} {\dfrac{\dfrac{\sqrt{1+x}-1}{x}-k}{x}}\\\\=\lim_{x\rightarrow0} {\dfrac{\dfrac{\sqrt{1+x}-1-kx}{x}}{x}}\\\\=\lim_{x\rightarrow0} {\dfrac{\sqrt{1+x}-1-kx}{x^2}}\\

Thank you
