Solve 4 over x minus 4 equals the quantity of x over x minus 4, minus four thirds for x and determine if the solution is extrane
Vinil7 [7]
I'm thinking this is what the problem looks like: \frac{4}{x-4}= \frac{x}{x-4}- \frac{4}{3}.  The first thing to do is to move the \frac{x}{x-4} over to the other side because it has a common denominator with the other side.  Doing that and at the same time combining them over their common denominator looks like this: \frac{4-x}{x-4}= -\frac{4}{3}.  The best way to solve for x now is to cross-multiply to get 3(4-x)=-4(x-4).  Distributing through the parenthesis is 12 - 3x = -4x + 16.  Solving for x gives us x = 4.  Of course when we sub a 4 back in for x we get real problems, don't we?  Dividing by zero breaks every rule in math that there ever was! So, yes, the solution is extraneous.

Please help I only have an hour. ​
Goshia [24]

Answer:

Slope (m) = \frac{y}{x} = \frac{2}{3} = 0.66666666666667

Step-by-step explanation:

0 = arctan (\frac{y}{x}) = 33.69006752598°

X = 4 – 1 = 3

Y = 4 – 2 = 2

Distance (d) = \sqrt{x^2+y^2}= \sqrt{13} =3.605551275464

Equation of the line:

y = 0.66666666666667x + 1.3333333333333

or

y=\frac{2}{3}x+\frac{4}{3}

When x=0, y = 1.3333333333333

When y=0, x = -2
