x = \frac{y - b}{c}

isolate xc by subtracting b from both sides

y - b = xc ( divide both sides by c )

x = \frac{y - b}{c}

Answer:

The value of the equation for y is x=\frac{y-b}{c}.

Step-by-step explanation:

Consider the provided equation.

y=xc+b

We need solve the above equation for x.

Subtract b from both the sides.

y-b=xc+b-b

y-b=xc

Divide c from both the sides.

\frac{y-b}{c}=\frac{xc}{c}

\frac{y-b}{c}=x

x=\frac{y-b}{c}

Thus, the value of the equation for y is x=\frac{y-b}{c}.

Hi could someone just help me with this I'm not sure if i'm doing it correctly.

Two angles are supplementary when they <span>add up to 180 degrees </span>⇒
m∠1 + m∠2 = 180°
4y + 7 + 9y + 4 = 180
13y + 11 = 180
13y = 180 - 11
13y = 169
y = 169/13
y = 13

m∠2 = 9y + 4 = 9 * 13 + 4 = 121°

Answer:

The perimeter of triangle is 30ft.

Step-by-step explanation:

First you have to find the value of a using Pythogoras Theorem, a² + b² = c² where a and b is the sides and c is the hypotenuse :

{a}^{2}  +  {b}^{2} =   {c}^{2}

{a}^{2}  =  {c}^{2}  -  {b}^{2}

a =  \sqrt{ {c}^{2} -  {b}^{2}  }

Let b = 12,

Let c = 13,

a =  \sqrt{ {13}^{2} - 12 {?}^{2}  }

a =  \sqrt{25}

a = 5feet

Next you have to find the perimeter of triangle by adding all the sides together :

perimeter = 5 + 12 + 13

perimeter = 30feet

Consider the function f(x)=3/4x+12 what is the y-intercept of f-1(x)
miskamm [114]

Answer:

y = -16

Step-by-step explanation:

f(x)=3/4x+12 (replace f(x) with y)

y =3/4x+12  (rearrange to express x in terms of y)

y - 12=3/4 x

3/4 x = y - 12

3x = 4(y - 12)

x = (4/3)(y - 12)

x = (4/3)y - (4/3)(12)

x = (4/3)y - 16

f^{-1} (y) = (4/3)y - 16

f^{-1} (x) = (4/3)x - 16

comparing to general form

y = mx + b where b is the y-intercept

b = -16

Hence the y-intercept is y = -16
