Answer 1

Answer:

. if x is inversely proportional to y and x = 40 when y = 5, find:a) The value of x ... pair of linear equation by substuation method 3x -y =3 and 4x +2y = 3.

Answer 2

Answer:

Given,

3x³ - 5x² + 4 if x = -2

Find,

the value

Step-by-step explanation:

So,

3*(-2)(-2)(-2) - 5 * (-2)(-2) + 4

Or. 3 * (-8) - 5*4 + 4

Or -24 - 20 + 4

Or -44 + 4

Or -40

Hence,

the value is -40
