In which direction will this parabola open? <br> x=53(y+17)^2-41

navik [9.2K]

$x=53(y+17)^2-41\\
x=53(y^2+34y+289)-41\\
x=53y^2+1802y+15317-41\\
x=53y^2+1802y+15276$

As a>0 so the concavity (open) of the parable is to the right.

If x^2=20 what is the value of x will give brainliest for answer

Schach [20]

Answer:

x² - 20 = 0

Using the quadratic formula

$x = \frac{ - b± \sqrt{( {b})^{2} - 4ac } }{2a}$

a = 1 b = 0 c = -20

So we have

$x = \frac{ - 0 ± \sqrt{ {0}^{2} - 4(1)( -20)} }{2(1)} \\ \\ x = \frac{± \sqrt{80} }{2} \\ \\ x = \frac{±4 \sqrt{5} }{2} \\ \\ \\ x = ±2 \sqrt{5} \\ \\ \\ x = 2 \sqrt{5} \: \: \: or \: \: \: x = - 2 \sqrt{5}$

Hope this helps you.
