Answer:

x=1.5

Step-by-step explanation:

You divide 8 by 8 and then -12 by 8. And then you get x=-1.5 because 8 divided by 8 is zero and -12 divided by 8 is -1.5

How do I solve this equation?

Gnom [1K]

$2x(4-x)^{-1/2}-3(4-x)^{1/2}=(4-x)^{-1/2}\bigg(2x-3(4-x)\bigg)$

We effectively rewrite the equation as

$\dfrac{5x-12}{(4-x)^{1/2}}=0$

In order for the LHS to be defined, we need to restrict $4-x>0$ , or $x$ . Now, the LHS will vanish when the numerator is 0, which happens for

$5x-12=0\implies5x=12\implies x=\dfrac{12}5$

This value is indeed smaller than 4, so the solution is $x=\dfrac{12}5$ .

Answer:

• Consider points (2, 0) and (0, 6) spotted from the graph.

${ \boxed{ \rm{slope = \frac{y _{2} - y _{1} }{x _{2} - x _{1} } }}}$

• substitute:

${ \rm{slope = \frac{6 - 0}{0 - 2} }} \\ \\ { \rm{ = \frac{6}{ - 2} }} \\ \\ { \boxed{ \boxed{ \tt{ \: \: slope = - 3 \: \: }}}}$
