Solve this system of equations, then determine what x equals. x + 5y= 7
2x + 4y = -4
X=-18 x=3
X=-8
X=7

Quickly multiply and simplify polynomials (x – 4) (x^2 – 5x – 6)

Aquality characteristic of new iphone x made at the amsterdam plant at apple computers has a manufacturing specification (in mm) of 0.200 +/- .07. historical data indicates that if the quality characteristic takes on values greater than 0.27 or smaller than 0.13 the component fails at a cost of20.19. based on these data: determine the taguchi loss function (must show work) calculate an estimated loss for a quality characteristic of .30 calculate an estimated loss for quality characteristic of .40.
