To make the problem more understandable... split the numbers you have 4 and negative 7. so remember that it is a negative number do 7-4, to get 3. But now remember it was a negative number so it would essentially be -3.

if you don't know what I did all I did was switch the number and keep the negative in the center, then I added the negative back to the equation to get my solution.

Answer:

One Solution

Step-by-step explanation:

Do distributive property

3k+6+3+7k=2k+4+3k

Combine like terms

10k+9=5k+4

Subtract 5k from 10k

5k+9=4

Subtract 9 from 4

5k=-5

Divide

k=-1

If f(x)=sinx 2x 1 and g is the inverse function of f
Bingel [31]

The value of the derivative of the function g(x) at x = 1 will be 1/3. Then the correct option is A.

<h3>What is an inverse function?</h3>

A function that may convert into another function is known as an inverse function or anti-function.

If the function is f(x) = sinx + 2x + 1.

Then the derivative of an inverse function g(x) of a function f(x) at a given value (a) will be

\rm g'(a) = \dfrac{1}{f'(g(a))}

The derivative of f(x) will be

f'(x) = cos x + 2

Then the given value of a will be

a = 1

g(x) = f⁻¹(x)

put x = 0, then we have

f(0) = sin 0 + 2(0) + 1

f(0) = 1

Put x = 1, in the function f⁻¹(x). Then we have

f⁻¹(1) = 0

and

g(1) = 0

Then put a = 1, then we have

\rm g'(a) = \dfrac{1}{f'(g(a))}\\\\g'(1) = \dfrac{1}{f'(g(1))}\\\\g'(1) = \dfrac{1}{f'(0)}\\\\g'(1) = \dfrac{1}{\cos 0 + 2}\\\\g'(1) = \dfrac{1}{1+2}= \dfrac{1}{3}

What is the equation that is perpendicular and passes through 8,3
ss7ja [257]
Y = 4x + 5
slope = 4
perpendicular, slope = - 1/4

passing thru (8,3)

equation
y - 3 = -1/4 (x - 8)
y - 3 = -1/4x + 2
y = -1/4x +5

answer is D. y = -1/4x +5
