Determine if the equation y = 2/5 x − 4 y=25x-4 represents a proportional relationship. If so, determine the constant of proport

Vilka [71]

Answer:

The linear equation represents a proportional relationship and its constant of proportionality is $k = \frac{2}{5}$ .

Step-by-step explanation:

A proportional relationship exists when the following relationship is observed:

$u = k\cdot v$

Where:

$u$ - Dependent variable.

$v$ - Independent variable.

$k$ - Proportionality constant.

If $y =\frac{2}{5}\cdot x - 4$ and $v = x$ and $u = y+4$ , the following expresion is found:

$y = \frac{2}{5}\cdot x -4$

$y + 4 = \frac{2}{5}\cdot x$

$u = \frac{2}{5}\cdot v$

The linear equation represents a proportional relationship and its constant of proportionality is $k = \frac{2}{5}$ .

Answer:

x = 5.7 units

Step-by-step explanation:

By applying Sine rule is the triangle XYZ,

$\frac{\text{SinX}}{\text{WY}}=\frac{\text{SinY}}{\text{WX}}=\frac{\text{SinW}}{\text{XY}}$

$\frac{\text{SinX}}{\text{x}}=\frac{\text{SinY}}{\text{y}}=\frac{\text{SinW}}{\text{10}}$

$\frac{\text{Sin33}}{\text{x}}=\frac{\text{SinY}}{\text{y}}=\frac{\text{Sin107}}{\text{10}}$

$\frac{\text{Sin33}}{\text{x}}=\frac{\text{Sin107}}{\text{10}}$

$x=\frac{10\times(\text{Sin33})}{\text{(Sin107)}}$

x = 5.69

x ≈ 5.7 units

Reduce to simplest form. -\dfrac{1}{3}-\left(-\dfrac{3}{5}\right)=− 3 1 −(− 5 3 )=minus, start fraction, 1, divided by, 3, e

nevsk [136]

Answer:

-1/3 - (-3/5) = 4/15

Step-by-step explanation:

Reduce to simplest form

-1/3 - (-3/5)

= -1/3 + 3/5

Find the Lowest Common Multiple of 3 and 5

Lowest Common Multiple of 3and 5 is 15

Use the LCM to Simplify

= {(-5*1)+(3*3)} / 15

= (-5+9) / 15

= 4/15

Therefore,

-1/3 - (-3/5) = 4/15
