Log ( base 2 ) ( 1 / 4 ) =
= log ( base 2 ) ( 2 ^(-2 ) ) =   
= - 2 log ( base 2 ) 2 =    ( because : log x^n = n log x )
= ( - 2 ) * 1 =    ( because:   log (base x) x = 1 )

What are the coordinates (x, y) at which the graphs of 3.6x − 2y = 6 and −2.7x + y = 3 intersect? Round to the nearest tenth if
Bas_tet [7]
3.6x - 2y = 6
-2.7x + y = 3.....multiply by 2
----------------
3.6x - 2y = 6
-5.4x + 2y = 6 (result of multiplying by 2)
----------------add
-1.8x = 12
x = 12/-1.8
x = - 6.67 (or -20/3)

3.6x - 2y = 6
3.6(-6.67) - 2y = 6
-24.01 - 2y = 6
-24.01 - 6 = 2y
-30.01 = 2y
-30.01 / 2 = y
-15 = y

solution : (-6.67, -15)

72.6

Step-by-step explanation:

Let second number be x.

First number= 6x

Third number= 3x

According to question,

6x+x+3x=121

or, 10x=121

or,x=121/10=12.1

First number= 6x=6×12.1=72.6

Third number=3x=3×12.1=36.3

Solve the equation for the y-value and choose whether it is a direct variation or inverse variation.
Leona [35]

\\ \sf\longmapsto xy=7

  • Take x to right and divide

\\ \sf\longmapsto y=\dfrac{7}{x}

Hence

.\\ \sf\longmapsto y\propto \dfrac{1}{x}

Inverse variation
