Question

(6y+25)*(1.2-0.2y)=0

Answer 1

Ответ:

y = -4 1/6; 6

Пошаговое объяснение:

(6y+25)(1.2-0.2y)=0

6y+25 = 0 или 1.2-0.2y = 0

6y = -25            0,2y = 1,2

y = -4 1/6            y = 6

Answer 2

To solve the equation (6y + 25) * (1.2 - 0.2y) = 0, you can use the zero-product property, which states that if the product of two factors is equal to zero, then at least one of the factors must be equal to zero. Therefore, you can set each factor equal to zero and solve for y separately.

First factor:

6y + 25 = 0

Subtract 25 from both sides:

6y = -25

Divide by 6:

y = -25/6

Second factor:

1.2 - 0.2y = 0

Subtract 1.2 from both sides:

-0.2y = -1.2

Divide by -0.2:

y = (-1.2) / (-0.2)

y = 6

So, the solutions to the equation are:

y = -25/6 and y = 6.
