2)-0,81*8 1/3= -0.81*25/3=-0.27*25/1=-6.75

Answer 2

To find the value of -0.81у at у = -4.5 and у = 8 1/3, you simply need to substitute the given values of у into the expression.

1. For у = -4.5: -0.81у = -0.81 * (-4.5) = 3.645

2. For у = 8 1/3: First, convert 8 1/3 to a decimal. 8 1/3 = 8.33 (rounded to two decimal places)

-0.81у = -0.81 * 8.33 = -6.7393 (rounded to four decimal places)

So, when у = -4.5, -0.81у is approximately 3.645, and when у = 8 1/3, -0.81у is approximately -6.7393.
