y=9x=3it equals ......y= 3.334
y=x+2if y=66=x+26-2=x4=xso x=4
y = 15 (by transitivity)
(x + y)2 = x2 + 2xy + y2 So x2 + y2 = (x + y)2 - 2xy = a2 - 2b Then (x2 + y2)2 = x4 + 2x2y2 + y4 So x4 + y4 = (x2 + y2)2 - 2x2y2 = (a2 - 2b)2 - 2b2 = a4 - 4a2b + 4b2 - 2b2 = a4 - 4a2b + 2b2
y=-7 but I have no idea on how to get it
If the question is, Is y = x4 an exponential function ? then the answer is no.An exponential function is one where the variable appears as an exponent.So, y = 4x is an exponential function.
y=x+2if y=66=x+26-2=x4=xso x=4
y=9x=3it equals ......y= 3.334
(x2 + y2)(x + y)(x - y) = x4 - y4.
y = 15 (by transitivity)

Y = 10x 10x = 40 y = 40
(x + y)2 = x2 + 2xy + y2 So x2 + y2 = (x + y)2 - 2xy = a2 - 2b Then (x2 + y2)2 = x4 + 2x2y2 + y4 So x4 + y4 = (x2 + y2)2 - 2x2y2 = (a2 - 2b)2 - 2b2 = a4 - 4a2b + 4b2 - 2b2 = a4 - 4a2b + 2b2
-1
it is equal to 6y plus y
y = 12. It's the transitive property. y = 12 = 3x.
y=-7 but I have no idea on how to get it
