1/12+3/8y=5/12+5/8y

3/8y- 5/8 y = 5/12- 1/12
-2/8y = 4/12
-1/4y = 1/3
y = 1/3 *(-4)
y = - 4/3

For which positive integer values of $k$ does $kx^2+20x+k=0$ have rational solutions? Express your answers separated by commas a

Musya8 [376]

Answer:

-10,10

Step-by-step explanation:

The given quadratic equation is

$k {x}^{2} + 20x + k = 0$

The discriminant of this equation is given by;

$D = {b}^{2} - 4ac$

where a=k, b=20, c=k

For rational solutions, the discriminant must be zero.

${20}^{2} - 4 \times k \times k = 0$

Simplify to get:

$400 - 4 {k}^{2} = 0$

This implies that:

$400 = 4 {k}^{2}$

$100 = {k}^{2}$

Take square root to get:

$k = \pm\sqrt{100}$

$k = \pm10$

$k = - 10 \: or \: k = 10$

Zielflug [23.3K]

Answer:

8.65 miles

Step-by-step explanation:

The total of his short runs are 9.35 so you need to find out how many miles he has left till he reaches 18 miles.

The equation you can use is 9.35 + x = 18 x will equal the number of miles for the long run.

9.35 + x = 18

to isolate x you will subtract 9.35 from both sides.

you will get:

x = 8.65

8.65 miles
