Question

12x - 8y + 1,2= 5,2варианты: (2;0), (0;-1),(1;4),(3;4)​

Answer 1

Ответ:

(1;4) кажется так но нез

Answer 2

Ответ: (3;4)

Объяснение: 12х -8у + 1,2 = 5,2

12х + 1,2 - 5,2 = 8у (ділим все на 8)

1,5х -0,5 = у

f(x)= 1,5х - 0,5

f(2)= 1,5*2 - 0,5 = 2,5 (2;0)​

f(0)= 1,5*0 - 0,5 = -0,5 (0;-0,5)​

f(1)= 1,5*1 - 0,5 = 0,5 (1;0,5)​

f(3)= 1,5*3 - 0,5 = 4 (3;4)​

Answer 3

To determine if the point (x, y) with the given values (x = 12 and y = -8) satisfies the equation 12x - 8y + 1.2 = 5.2, you can substitute these values into the equation and see if the equation holds true:

12(12) - 8(-8) + 1.2 = 5.2

Now, let's calculate the left-hand side of the equation:

144 + 64 + 1.2 = 209.2

So, with the point (x = 12, y = -8), the equation becomes:

209.2 = 5.2

The equation is not satisfied because 209.2 is not equal to 5.2.

Therefore, the point (12, -8) does not satisfy the equation, and none of the provided options (2;0), (0;-1), (1;4), or (3;4) satisfy the equation either.
