Question

-0,3x-13xy²-37ху², якщо х=4, y=-0,2.​ помогите ПОЖАЛУЙСТА

Answer 1

Объяснение:

Решение:

0,3x-13xy²-37ху² = - 7,8

При х=4 ; у=-0,2

0,3x-13xy²-37ху² = 0,3*4 - 13*4*(-0,2) ^2 - 37*4*(-0,2) ^2 = 1,2 - 52*0,04 - 148*0,04 = 1,20 - 2,08 - 5,92 = 1,20 - 8,00 = - 7,8

Ответ: -7,8

Answer 2

To find the value of the expression -0.3x - 13xy² - 37xu² when x = 4 and y = -0.2, we can substitute these values into the expression and simplify.

Substituting x = 4 and y = -0.2 into the expression, we get:

-0.3(4) - 13(4)(-0.2)² - 37(4)(-0.2)²

Simplifying each term:

-0.3(4) = -1.2 -13(4)(-0.2)² = -13(4)(0.04) = -13(0.16) = -2.08 -37(4)(-0.2)² = -37(4)(0.04) = -37(0.16) = -5.92

Now, substituting these simplified values back into the expression:

-1.2 - 2.08 - 5.92

Simplifying further:

-1.2 - 2.08 - 5.92 = -9.2

Therefore, when x = 4 and y = -0.2, the value of the expression -0.3x - 13xy² - 37xu² is -9.2.
