The product of y and -z is equal to -yz. When multiplying a positive number by a negative number, the result is negative. Therefore, y times -z is equal to -yz.
x=abs(y+z) x=+(y+z)=y+z x=-(y+z)=-y-z
this is very hard to write out without superscripts so it would be written out like this: y= k times x times cubed root of z if this was all reduced it would be: y=kx(z^1/3 ) i think this is right. >_< i hope this helped!
If x y and y z, which statement is true
It is not easy to illustrate this in a table since it would need to be a 3-d table. The browser which we are required to use is bad enough for ordinary tables. So here goes:X = True, Y = True, Z = True then (X or Y or Z) = TrueX = True, Y = True, Z = False then (X or Y or Z) = TrueX = True, Y = False, Z = True then (X or Y or Z) = TrueX = True, Y = False, Z = False then (X or Y or Z) = TrueX = True, Y = True, Z = True then (X or Y or Z) = TrueX = True, Y = True, Z = False then (X or Y or Z) = TrueX = True, Y = False, Z = True then (X or Y or Z) = TrueX = True, Y = False, Z = False then (X or Y or Z) = FalseThe simple way to remember is that the OR gate gives False only when each input is False.
x + 1 = y y + 3 = z z = y + 3 = (x + 1) + 3 = x + 4 Or: x = y - 1 = (z - 3) - 1 = z - 4 Which results in the same: x exceeds z by 4.
