Find the value of k and x2<br> x^2+ 13x + k = 0, x1=-9

Anarel [89]

Given:

The quadratic equation is:

$x^2+13x+k=0$

$x_1=-9$

To find:

The value of k and $x_1$ .

Solution:

We have,

$x^2+13x+k=0$ ...(i)

Putting $x=-9$ , we get

$(-9)^2+13(-9)+k=0$

$81-117+k=0$

$-36+k=0$

$k=36$

Putting $k=36$ in (i), we get

$x^2+13x+36=0$

Splitting the middle term, we get

$x^2+9x+4x+36=0$

$x(x+9)+4(x+9)=0$

$(x+9)(x+4)=0$

$x=-9,-4$

Here, $x_1=-9$ and $x_2=-4$ .

Therefore, the required values are $k=36$ and $x_2=-4$ .

Rex mixed x liters of fruit syrup with y liters of water to make a fruit punch. Three times the number of liters of water he mix

irga5000 [103]

3y = 2x + 6
x + y = 7

y = 7 - x
3(7 - x) = 2x + 6
21 - 3x = 2x + 6
21 - 6 = 2x + 3x
15 = 5x
15/5 = x
3 = x

x + y = 7
3 + y = 7
y = 7 - 3
y = 4

Solution is (3,4)
