Answer:

$(x - y) [3(x - y) - 2]$

Step-by-step explanation:

$3(x - y)^{2} - 2(x - y)$

Lets take $(x - y)$ common from the expression.

$=> (x - y) [3(x - y) - 2]$

Determine the equation of the tangent of the hyperbola that is parallel to the given line:

marin [14]

The tangent line to the curve has slope equal to $\frac{\mathrm dy}{\mathrm dx}$ . Use implicit differentiation to find this derivative.

$9x^2-4y^2=32$

$\implies18x-16y\dfrac{\mathrm dy}{\mathrm dx}=0\implies\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{-18x}{-16y}=\dfrac{9x}{8y}$

The given line in slope-intercept form is

$9x+2y-1=0\implies y=\dfrac{1-9x}2$

and has slope -9/2. Any line parallel to this one has the same slope. The tangent to the hyperbola has this slope at points (<em>x</em>, <em>y</em>) such that

$-\dfrac92=\dfrac{9x}{8y}\implies x=-4y$

Find the points on the hyperbola where this condition is met.

$9(-4y)^2-4y^2=140y^2=32\implies y^2=\dfrac{32}{140}\implies y=\pm\sqrt{\dfrac8{35}}\implies x=\pm4\sqrt{\dfrac8{35}}$

Then use the point-slop formula to build the equations of these tangents:

$y\mp\sqrt{\dfrac8{35}}=-\dfrac92\left(x\pm4\sqrt{\dfrac8{35}}\right)$

Answer:

-4m + 6 = 14

Explanation:

You subtract 3m from both sides of the equal sign, meaning:

-m - 3m;

and 3m - 3m.

Both 3m cancels out, and since -m = -1m, you subtract like normal.

-1 - 3 = -4.

So then, you just rewrite the equation.

-4m + 6 (from the original) = 14 (3m is gone now because you canceled it out/subtracted it out.)
