Add n on both sides:

3m = km - 8 + n

Subtract km on both sides:

3m - km = n - 8

Factor the Left-Hand Side:

m(3 - k) = n - 8

Divide both sides by (3 - k):

m = (n - 8) / (3 - k)

Answer:

(8-n)/(k-3) =m

Step-by-step explanation:

3m-n=km-8

Subtract 3m from each side

3m -3m-n=km -3m-8

-n =km -3m-8

Add 8 to each side

8-n =km -3m-8+8

8-n =km -3m

Factor out m

8-n =m(k -3)

Divide by (k-3)

(8-n)/(k-3) =m(k -3)/( k-3)

(8-n)/(k-3) =m

Sindrei [870]

Answer:

See steps below

Step-by-step explanation:

Let F(x, y) and W be

F(x,y) = “x can fool y”

W the set of all the people in the world

a) Everybody can fool Fred.

$\forall x \in W,F(x, Fred)$

b) Evelyn can fool everybody.

$\forall y\in W, F(Evelyn, y)$

c) Everybody can fool somebody.

$\forall x \in W,\exists y :F(x,y)$

d) There is no one who can fool everybody.

$\nexists x \in W: \forall y ,F(x,y)$

e) No one can fool both Fred and Jennifer.

$\nexists x \in W: F(x,Fred)\wedge F(x,Jennifer)$

f) Nancy can fool exactly two people.

$\exists x,y \in W:\forall z\neq x,z\neq y, F(Nancy,x)\wedge F(Nancy,y)\wedge (\neg F(Nancy,z))$

find the equation of the line using the point slope formula. write the final equation using the slope intercept for thr x-interc

aleksley [76]

we know the x-intercept of the line is 1, recall that an x-intercept is when the graph intercepts or touches the x-axis, and when that happens, y = 0, so the point is really x = 1, y = 0, namely (1,0). We also know another point on the line, is (-2, 9).

$\bf \stackrel{x-intercept}{(\stackrel{x_1}{1}~,~\stackrel{y_1}{0})}\qquad (\stackrel{x_2}{-2}~,~\stackrel{y_2}{9}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{9-0}{-2-1}\implies \cfrac{9}{-3}\implies -3 \\\\\\ \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-0=-3(x-1) \\\\\\ ~\hspace{10em}y=-3x+3$
