Question

5-5х при х= 1 и х =-1

Answer 1

Если х=1, то
5-5*1=5-5=0

Если х=-1, то
5-5*(-1)=5+5=10

Answer 2

To evaluate the expression 5 - 5x at x = 1 and x = -1, we substitute the given values into the expression and perform the calculations.

At x = 1: 5 - 5(1) = 5 - 5 = 0

At x = -1: 5 - 5(-1) = 5 + 5 = 10

Therefore, when x = 1, the value of 5 - 5x is 0, and when x = -1, the value is 10.
