1 answer:

4 0

3. 2x - y = 10
    2x - 2x - y = -2x + 10
   -y = -2x + 10
   -1    -1
   y = 2x - 10
   Slope: 2

4. 5x - 2y = 10
    5x - 5x - 2y = -5x + 10
   -2y = -5x + 10
      -2 -2
      y = 2.5x - 5

5. y - y₁ = m(x - x₁)
    y - (-2) = -3(x - (-1))
   y + 2 = 3(x + 1)
   y + 2 = 3(x) + 3(1)
   y + 2 = 3x + 3
   - 2    - 2
   y = 3x + 1

4. Which of the following expressions represents the perimeter of the figure below?

Alexxx [7]

<h2>Explanation:</h2><h2 />

Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll help you assuming some things. First of all, for a two dimensional shape, the perimeter is defined as the distance around it. Suppose we have a rectangle whose dimensions are:

$l=4x+9 \\ \\ w=2x-19 \\ \\ \\ l:Length \\ \\ w:Width \\ \\ \\ \text{So the perimeter is:} \\ \\ P=2l+2w \\ \\ P=2(4x+9)+2(x-19) \\ \\ P=8x+18+2x-38 \\ \\ P=(8x+2x)+(18-38) \\ \\ \boxed{P=10x-20}$

So in this context:

Correct option is D. 10x - 20
