The roots of the quadratic equation $ax^2+bx+c=0$ are

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

Here the given quadratic equation is $5x^2-13x+7=0$ . Here $a=5,b=-13,c=7$ .

The roots are

$x=\frac{13 \pm \sqrt{13^2-4*5*7}}{2*5} \\ x=\frac{13 \pm \sqrt{29}}{10}$

If y varies directly as x, and y is 20 when x is 4, what is the constant of variation for this relation?

Ludmilka [50]

Answer:

Step-by-step explanation:

y = k*x This is the formula for a direct variation.

y = 20
x = 4 Substitute these values into the direct variation

20 = 4 * k Divide by 4

20/4 = 4k/4

k = 5

Answer: the constant of variation is 5
