Answer:

               -\dfrac67

Step-by-step explanation:

slope of r:

                  a_r=\dfrac{10-3}{8-2}=\dfrac76

s is perpendicular to r:

s\perp r\ \ \implies\ \ a_s\cdot a_r=-1\\\\a_s\cdot\dfrac76=-1\\\\a_s=-\dfrac67

Which equation can be simplified to find the inverse of y = 2x ^ 2 ?
Rama09 [41]

Answer:

D)x = 2y ^ 2

Step-by-step explanation:

y = 2x ^ 2

To find the inverse exchange x and y

x = 2 y^2

Then solve for y

Divide by 2

x/2 = 2y^2 /2

x/2 = y^2

Take the square root of each side

±sqrt(x/2) = y
