If x-1/3 = k and k = 3, what is the value of x ? A) 2 B) 4 C) 9 D) 10

Semenov [28]

Answer:

None of the above

Step-by-step explanation:

x-1/3 = k

We know that k=3, so we can substitute that into the equation

x-1/3 = 3

Add 1/3 to each side

x-1/3 + 1/3 = 3+1/3

x = 3 1/3 or as an improper fraction 10/3

If y varies directly as the square root of x and y=12 when x = 16 , find x when y = 15

a_sh-v [17]

= 19 this is the answer I'm guessing since 16-12= 4 so 16 is 4 more than 12

Can someone get this? Ive been trying and cant get it

Dmitry [639]

Given :-

The roots of the function are 5 and -3 .

To Find :-

The Quadratic function .

Answer :-

The roots of the function are 5 and -3 . In general we can write the Quadratic function with roots π and ∆ as ,

$\sf\longrightarrow$ f(x) = ( x - π )(x-∆)

So on using this we have ,

$\sf\longrightarrow$ f(x) = ( x -5)( x -(-3))

$\sf\longrightarrow$ f(x) = (x-5)(x+3)

$\sf\longrightarrow$ f(x) = x(x-5)+3(x-5)

$\sf\longrightarrow$ f(x) = x² -5x +3x -15

$\sf\longrightarrow$ f(x) = x² -2x -15

Hence the required answer is x² -2x -15.
