Determine the following<br>quadratic equations have real<br>roots<br><br>1) 3x² - √2x-√3​
IceJOKER [234]

Step-by-step explanation:

√3 x² - 2x - √3 = 0

√3 x² - 3x + x - √3 = 0

√3 x(x - √3) + 1(x - √3) = 0

(x - √3 ) (√3 x + 1) = 0

x - √3 = 0 , √3 x +1 = 0

x = √3 , x = -1/√3

Find the slope of the line that contains the<br><br>point (4, −9) and has a y intercept of 2.
ASHA 777 [7]

Answer:

<h2>         m = -¹¹/₄</h2>

Step-by-step explanation:

The equation of a line with slope of <em>m</em> and y-intercept of <em>b</em> is: y = mx + b

b = 2 and line contains the point (4, -9), so:

-9 = m×4 + 2          {subtract 2 from both sides}

-11 = 4m                   {divide booth sides by 4

m = -¹¹/₄
