\huge{ \mathfrak{  \underline{ Answer \:  \:  ✓ }}}

Slope of the line :

\large\boxed{ \mathrm{ \frac{y_2 - y_1 }{x_2 - x_1} }}

  • \dfrac{7 - 2}{ - 2 - 3}

  • \dfrac{ 5}{ - 5}

  • - 1

therefore, m = slope = -1

The equation of the line will be :

  • y = mx + b

  • y = (-1 × x) + b

  • y = -x + b

Now, let's plug the value of x and y from coordinates of second point,

  • y =  - x + b

  • 2 =  - 3 + b

  • b = 5

Hence, the required values are :

  • \boxed{m =  - 1}

  • \boxed{  \:  \:  \: b = 5 \:  \:  \:  }

Answer:

m = - 1

b = 5

Step-by-step explanation:

slope, m= \frac{2-7}{3--2}= \frac{-5}{5}= -1\\\\equation : (y-y_1)= m(x-x_1)

             (y-7) = -1(x--2)\\y-7 = -1(x+2)\\y = -1x-2+7\\y= -1x+5

Trava [24]

Answer:

RH = 8.2 units

Step-by-step explanation:

total circumference = 2rπ = 2(10)(3.14) = 62.8 units

RH = (47°/360°)(62.8) = 8.2 units

If f(x) =1/9 x-2, what is f-1(x)?
Sav [38]

Answer:

f^-1(x) = 9(x+2)

Step-by-step explanation:

To find the inverse function, exchange x and y and then solve for y

y = 1/9 x -2

Exchange x and y

x = 1/9 y-2

Solve for y

Add 2 to each side

x+2 = 1/9 y-2+2

x+2 = 1/9y

Multiply each side by 9

9(x+2) = 9*1/9y

9(x+2) = y

The inverse function

f^-1(x) = 9(x+2)
