Question

18xy+6x-24y,при x=1 и y=0,45

Answer 1

18xy + 6x - 24y = 18*1*0,45 + 6*1 - 24*0,45 = 18*0,45 + 6 - 24*0,45 = -6*0,45 + 6 = -2,7 + 6 = 3,3

Answer 2

To evaluate the expression 18xy + 6x - 24y when x = 1 and y = 0.45, simply substitute these values into the expression and perform the calculations:

18xy + 6x - 24y = 18(1)(0.45) + 6(1) - 24(0.45) = 18(0.45) + 6 - 10.8 = 8.1 + 6 - 10.8 = 3.3

So, when x = 1 and y = 0.45, the expression 18xy + 6x - 24y evaluates to 3.3.
