Answer:
Step-by-step explanation:
Plug x for y and y for x.
y = 2x^2 + 2
x = 2y^2 + 2
Then isolate the y variable.
x - 2 = 2y^2
sqrt(x - 2) = 2y
(sqrt(x - 2))/2 = y
Answer:
Step-by-step explanation:
so the dvd player is 984 dollars so now we multiply it by three and our total would be 2,952
I got 26.43. I'm not sure if it is completely correct though
The formula for the discriminant is the square root of b^2 - 4ac
8x^2+18x-5= 0
a = 8, b=18, c= -5
Square root of 324 +160
Square root of 484 = 22 The discriminant is 22
