What is the solution to the equation below. square root x - 6 = x - 12

lyudmila [28]

$\\ \rm\hookrightarrow \sqrt{x-6}=x-12$

$\\ \rm\hookrightarrow x-6=(x-12)^2$

$\\ \rm\hookrightarrow x-6=x^2-24x+144$

$\\ \rm\hookrightarrow x^2-25x+150=0$

$\\ \rm\hookrightarrow x^2-10x-15x+150=0$

$\\ \rm\hookrightarrow (x-10)(x-15)=0$

$\\ \rm\hookrightarrow x=15\:or \:10$

Find all constants a such that the vectors (a, 4) and (2, 5) are parallel.

Nezavi [6.7K]

Answer:

$\displaystyle a = \frac{8}{5}$ .

Step-by-step explanation:

Two vectors $(x_1,\, y_1)$ and $(x_2,\, y_2)$ are parallel to one another if and only if the ratio between their corresponding components are equal:

$\displaystyle \frac{x_1}{x_2} = \frac{y_1}{y_2}$ .

Equivalently:

$\displaystyle \frac{x_1}{y_1} = \frac{x_2}{y_2}$ .

For the two vectors in this equation to be parallel to one another:

$\displaystyle \frac{a}{4} = \frac{2}{5}$ .

Solve for $a$ :

$\displaystyle a = \frac{8}{5}$ .

$\displaystyle \frac{8}{5}$ would be the only valid value of $a$ ; no other value would satisfy the $\displaystyle \frac{x_1}{y_1} = \frac{x_2}{y_2}$ equation.
