Question

125x • (–0,8y) если x = –1,3 , y = 6.

Answer 1

125(-1,3) • (-08•6)=-162,5•(-4,8)=780

Answer 2

To evaluate the expression 125x • (-0.8y) when x = -1.3 and y = 6, we substitute the given values into the expression and perform the calculations.

125x • (-0.8y) = 125 * (-1.3) • (-0.8 * 6)

Let's calculate each part of the expression step by step:

125 * (-1.3) = -162.5

-0.8 * 6 = -4.8

Now, substitute these values back into the expression:

-162.5 • -4.8

Multiplying two negative numbers gives a positive result:

= 780

Therefore, when x = -1.3 and y = 6, the value of the expression 125x • (-0.8y) is 780.
