Question

-3,5х + 6 при х=2;-3; 0,4

Answer 1

-3,5*2+6=-7+6=-1
-3,5*(-3)+6=10,5+6=16,5
-3,5*0,4+6=-1,4+6=4,6

Answer 2

To find the values of the expression -3 + 5x + 6 when x takes the values of 2, -3, and 0.4, we simply substitute these values into the expression and perform the calculations.

Let's calculate for each value of x:

1. When x = 2: -3 + 5(2) + 6 -3 + 10 + 6 = 13

2. When x = -3: -3 + 5(-3) + 6 -3 - 15 + 6 = -12

3. When x = 0.4: -3 + 5(0.4) + 6 -3 + 2 + 6 = 5

So, the values of the expression -3 + 5x + 6 when x is 2, -3, and 0.4 are 13, -12, and 5, respectively.
