5x^2+11x=0 quadratic equation

hammer [34]

$5x^{2} + 11x = 0
$
$5x^{2} + 11x + 0 = 0$
$x = \frac{-(11) +/- \sqrt{(11)^{2} - 4(5)(0)}}{2(5)}$

$x = \frac{-11 +/- \sqrt{121 - 0}}{10}$

$x = \frac{-11 +/- \sqrt{121}}{10}$

$x = \frac{-11 +/- 11}{10}$

$x = \frac{11 + 11}{10}$    $x = \frac{11 - 11}{10}$

$x = \frac{22}{10}$          $x = \frac{0}{10}$

$x = 2.2$       $x = 0$

the vertex of this parabola is at (5,5). when the x-value is 6, the y-value is -1. what is the coefficient of the squared in the

zlopas [31]

Answer: OPTION D.

Step-by-step explanation:

The vertex form of a quadratic function is:

$y= a(x - h)^2 + k$

Where (h, k) is the vertex of the parabola and "a" is the coefficient of the squared in the parabola's equation.

We know that the vertex of this parabola is at (5,5) and we also know that when the x-value is 6, the y-value is -1.

Then we can substitute values into $f (x) = a(x - h)^2 + k$ and solve for "a". This is:

$-1= a(6- 5)^2 + 5\\\\-1=a+5\\\\-1-5=a\\\\a=-6$

Graph m=3 b=-1 m=-2 b=4

Fittoniya [83]

Answer:

y= 3x − 4

Step-by-step explanation:

The slope-intercept form for a linear equation is

y= mx + b, where m = the slope, and b = the y-intercept.

Given:

m= 3 and b = −4

y= 3x - 4

Please help me find x thank you so much :)

lesya692 [45]

Answer:

x= 27

Step-by-step explanation:

a triangle always has 180 degrees, therefore:

(3x-17)+(x+40)+(2x-5)= 180

6x+18=180

6x=162

x=162/6

x=27
