Solving 6x^2-24x-54 with quadratic formula

Mathematics

Answer:

x = 5.61 or -1.61

Step-by-step explanation:

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

6x² - 24x - 54 = 0

6(x² - 4x - 9) = 0

x = [4+-√(4²)-4(1)(-9)]/2(1)

= (4+√52)/2

= 5.61

= (4-√52)/2

= -1.61

Passing through point (4, 9) and perpendicular to the line y= -1/5x -3

Ratling [72]

Answer:

y = 5x-11

Step-by-step explanation:

The slope intercept form of a line is y =mx+b where m is the slope

y = -1/5 x-3

The slope is -1/5

Lines that are perpendicular have negative reciprocal slopes

-1 /(-1/5)

-1 * -5/1

The slope of the line that is perpendicular is 5

y=5x+b

Using the point (4,9)

9 = 5(4)+b

9 = 20+b

9-20 =b

-11

y = 5x-11
