What is the quadratic formula of #0=10x^2 + 9x-1#?

natali 33 [55]

Quadratic formula is:

$x = \frac{- b +/- \sqrt{ b^{2} - 4ac} }{2a}$

Plug in:

$x = \frac{-9 +/- \sqrt{9^{2} - 4(10)(-1)} }{2(10)}$

$x = \frac{-9 +/- \sqrt{81 + 40}}{20}$

$x = \frac{- 9 +/- \sqrt{121}}{20}$

$x = \frac{- 9 +/- 11}{20}$

$x = \frac{-9 - 11}{20}$ and $x = \frac{- 9 + 11}{20}$

$x = \frac{- 20}{20}$ and $x = \frac{2}{20}$

$x = - 1, \frac{1}{10}$

Find the equation of a line that has a slope of 1/2 and passes through the origin.

omeli [17]

Step-by-step explanation:

The equation of a line with slope m and y-intercept b is y = m x + b.

This line goes through the point ( 0 ,0 ), so the y-intercept is zero.

We are given the slope as − 2 / 3.

The equation of the line is y= – 2 / 3 x + 0 = – 2 / 3 x

y = – 2 / 3 x
