What is the expression (x-3)(x^2-3x-10) as a polynomial in standard form?

1 answer:

5 0

A polynomial in standard form only means that you put it in order of descending x values. Multiplying out those 2 factors gives us $x^3-3x^2-10x-3x^2+9x+30$ . Combining like terms and we have $x^3-6x^2-x+30$ . That's in standard form.

Answer:

A traditional economy is a system that relies on customs, history, and time-honored beliefs. Tradition guides economic decisions such as production and distribution. Societies with traditional economies depend on agriculture, fishing, hunting, gathering, or some combination of them. They use barter instead of money.

Graph the image of △UVW after a reflection over the line y=-x

Answer:

Step-by-step explanation:

Reflection over the line x = -1 alters the x-coordinates, but leaves the y-coordinates alone. The image point is as far horizontally from the reflection line as the pre-image point is. Each new x-coordinate is the old one subtracted from twice the x-value of the line of reflection: (x, y) ⇒ (-2-x, y) U(-8, -6) ⇒ U'(6, -6) V(-3, -6) ⇒ V'(1, -6) W(-4, -1) ⇒ W'(2, -1)
