Answer:

B.) 3√15

Step-by-step explanation:

a^2 + b^2 = c^2

x^2 + 11^2 = 16^2

x^2 + 121 = 256

x^2 = 256 - 121

x^2 = 135

√x^2 = √135

√135 = √9 • √15

√9 = 3

√15 = √15

3√15

What is 2x+8y=12 in slope intercept form <br>as well as x-2y=0 in slope intercept form

earnstyle [38]

$the \ slope \ intercept \ form \ is : \\ \\ y= mx +b \\ \\ 2x+8y=12 \ \ |-2x \\ \\8y=-2x+12\ \ /:8\\ \\y=-\frac{2}{8}x+\frac{12}{8}$

$y=-\frac{1}{4}x+\frac{3}{4}\\ \\ m=-\frac{1}{4}$

$x-2y=0 \ \ | -x \\ \\-2y=-x \ \ /:(-2)\\ \\y=\frac{1}{2}x \\ \\ m= \frac{1}{2}$
