Question

Вычисли значение выражения ax−9y, при a= 20, x= −15, y=−19. ax−9y =

Answer 1

20×(-15)-9×(-19)=-300-(-171)=-300+171 =-129

Answer 2

To calculate the value of the expression ax - 9y with given values, simply substitute the given values of a, x, and y into the expression:

a = 20 x = -15 y = -19

ax - 9y = (20 * -15) - (9 * -19)

Now, perform the calculations step by step:

ax - 9y = (-300) - (-171) ax - 9y = -300 + 171 ax - 9y = -129

So, the value of the expression ax - 9y, with a = 20, x = -15, and y = -19, is -129.
