Indicate the equation

KiRa [710]

Answer:

Slope - intercept form

$y = \frac{3}{5} x - \frac{26}{5}$

Step-by-step explanation:

Step(i):-

Given that the point (2,-4) and slope $m = \frac{3}{5}$

Equation of the straight line passing through the point (x₁, y₁) and slope 'm'

y - y₁ = m( x-x₁ )

y - (-4) = $\frac{3}{5}$ ( x-2)

⇒ 5( y+4) = 3(x-2)

⇒ 5 y +20 = 3x -6

⇒ 3x - 5 y -6-20 =0

⇒ 3 x -5y -26=0

Step(ii):-

Slope - intercept form

5 y = 3x -26

$y = \frac{3}{5} x - \frac{26}{5}$

What is x= (2/5) to the third power?

Anton [14]

Answer:

x = $\frac{8}{125}$ or $0.064$

Step-by-step explanation:

Write it out: $x = (\frac{2}{5}) ^{3}$
$\frac{2}{5} ^{3} = \frac{8}{125}$
$\frac{8}{125} = 0.064$
So, x equals $\frac{8}{125}$ or $0.064$

I hope this helps!
