Select all of the following ordered pairs that are in the solution set of the inequality shown.
Irina-Kira [14]

Answer:

  • points on the boundary line: (0, 10), (20, 0)
  • solution points not on the boundary line: (100, 100)

Step-by-step explanation:

We cannot tell from the posted picture whether the boundary line is solid or dashed, so the answer above is split into two parts. If the boundary line is solid (x+2y≥20), all three listed points are in the solution set. If the boundary line is dashed (x+2y>20), only (100, 100) is in the solution set.

Answer:

<em>(a) x(x+2)  (b) 2x(x-3)  (c) 5x(3-2x^2)  (d) 3x^2(3+x)</em>

Step-by-step explanation:

For each expression, <u>we need to factor out the GCF(Greatest common factor)</u>

a)   x^2+2x

Here, the GCF is  x. So, we will get.....

x^2+2x\\ \\ =x(\frac{x^2}{x}+ \frac{2x}{x}) \\ \\ =x(x+2)

b)   2x^2-6x

Here, the GCF is  2x. So, we will get......

2x^2-6x\\ \\ =2x(\frac{2x^2}{2x}- \frac{6x}{2x}) \\ \\ =2x(x-3)

c)   15x-10x^3

Here, the GCF is  5x. So, we will get.......

15x-10x^3\\ \\ =5x(\frac{15x}{5x}- \frac{10x^3}{5x}) \\ \\ =5x(3-2x^2)

d)   9x^2+3x^3

Here, the GCF is  3x^2. So, we will get.......

9x^2+3x^3\\ \\ =3x^2(\frac{9x^2}{3x^2}+ \frac{3x^3}{3x^2}) \\ \\ =3x^2(3+x)
