Question

8x - 12y при x = 0, y = -12; x = -1,5, y = 3

Answer 1

1. 8*0-12*(-12)=0+144=144; 2. 8*(-1,5)-12*3= -12-36= -48.

Answer 2

To find the value of the expression 8x - 12y given different values of x and y, we can substitute the values into the expression and calculate the result.

1. When x = 0 and y = -12: 8x - 12y = 8(0) - 12(-12) = 0 + 144 = 144

2. When x = -1.5 and y = 3: 8x - 12y = 8(-1.5) - 12(3) = -12 - 36 = -48

Therefore, when x = 0 and y = -12, the value of 8x - 12y is 144, and when x = -1.5 and y = 3, the value of 8x - 12y is -48.
