Answer:

\frac{2}{9} x

Step-by-step explanation:

To find slope using two points you need to find the difference in x and y. You use \frac{y_{2}-y_{1}}{x_{2}-x_{1} }

So, 2-0=2 and 5-(-4)=9. Therefore the slope is 2/9x

The length of a rectangle is 2 units shorter than one-fifth of the width, x.
sergey [27]

Answer:

C. P=\frac{12x}{5} + 4

Step-by-step explanation:

Width = x

Length = one fifth of width minus 2

Length = \frac{1}{5}x-2

Perimeter is given by the formula

P=2(l+b)

P=2(\frac{1}{5}x-2+x)

P=2(\frac{x}{5}-2+x)

P=2\times \frac{x-2 \times 5+5 \times x}{5}

P=2\times \frac{x-10+5x}{5}

P=2\times \frac{6x}{5} - 2\times \frac{-10}{5}

P=2\times \frac{6x}{5} + 2\times \frac{10}{5}

P=\frac{12x}{5} + 4
