Y=kx, k is not equal to 0
when y=32,x=3, 32=3k
k=32/3
so y=32/3*x
when y=15, 15=32/3*x
x=45/32

Which is the solution of the equation 1/4 ( 3x - 1 ) = 2x -2/3

agasfer [191]

Answer:

x = 1/3

Step-by-step explanation:

Perform the indicated multiplication:

Clear out the fractions. The LCD here is 12, so multiply both sides by 12, obtaining:

3(3x - 1) = 24x - 8, or

9x - 3 = 24x - 8

Combining like terms, we get 5 = 15x, so that x = 1/3.

oksano4ka [1.4K]

Answer:

$\frac{1}{8xy \sqrt{y} }$

Step-by-step explanation:

$(64 {x}^{2} {y}^{3} )^{ - \frac{ 1 }{2} } \\ \\ = \frac{1}{(64 {x}^{2} {y}^{3} )^{\frac{ 1 }{2} } } \\ \\ = \frac{1}{ \sqrt{64 {x}^{2} {y}^{3}} } \\ \\ = \frac{1}{ \sqrt{ {(8xy)}^{2} y} } \\ \\ = \frac{1}{8xy \sqrt{y} }$
