Question

1- 7 + 30у при у = -0,1.​

Answer 1

$1-7+30y, y=-0.1\\1-7+30*(-0.1)=1-7-3=-9$

Answer 2

To evaluate the expression 1-7+30у when у = -0.1, we substitute the value of у into the expression and perform the calculations.

Substituting у = -0.1 into the expression, we have:

1 - 7 + 30*(-0.1)

Now let's simplify the expression step by step:

1 - 7 = -6

-6 + 30*(-0.1)

-6 + (-3) = -9

Therefore, when у = -0.1, the expression 1-7+30у evaluates to -9.
