The solutions to the given quadratic equation can be determined using quadratic formula.

$x= \frac{-b+- \sqrt{ b^{2} -4ac} }{2a}$

b =coefficient of x term = -1
a = coefficient of squared term = 4
c = constant term = 9

Using the values in the above formula we get:

$x= \frac{1+- \sqrt{1-4(4)(9)} }{2(4)} \\ \\ 
x= \frac{1+- \sqrt{-143} }{8} \\ \\ 
x= \frac{1+-i \sqrt{143} }{8}$

So, option D gives the correct answers

The variables x and y vary directly. Write an equation that relates x and y, when x = 4 and y = 2

Sholpan [36]

Since x & y vary directly (it means when x increases, y increases & vice versa)
Then the equation==> y = k.x (k is a constant to be calculated)

But x=4 and y= (given) ==> 2=4k or k= 1/2 & the equation becomes <span>y=1/2 (x)</span>

Which calculation correctly uses prime factorization to write V48 in simplest form?

SVETLANKA909090 [29]

Answer:

$\sqrt{48} = \sqrt{2 \times 2 \times 2 \times 2 \times 3} \\ = \sqrt{16 \times 3} \\ = 4 \sqrt{3}$
