If polygons are similar ratio if sides will be same

$\\ \sf\longmapsto \frac{x}{50} = \frac{48}{40} \\ \\ \sf\longmapsto 40x = 48 \times 50 \\ \\ \sf\longmapsto x = \frac{48 \times 50}{40} \\ \\ \sf\longmapsto x = \frac{2400}{40} \\ \\ \sf\longmapsto x = 60$

Tell weather the lines for each pair of equations are parallel perpendicular or neither y=-1/5x+6

FinnZ [79.3K]

Answer:

The slopes are neither perpendicular nor parallel.

Step-by-step explanation:

First we are going to find the slope-inercept form from the equation, -2x + 10y = 5.

Solve for y.

-2x + 10y = 5

+2x. = +2x

10y = 2x + 5

$\begin{gathered} \frac{10y}{10} = \frac{2x + 5}{10} \\ y = \frac{1}{5}x + \frac{1}{2} \end{gathered}$

So we now have

$\begin{gathered}y = \frac{1}{5}x + \frac{1}{2} \\ and \\ y = - \frac{1}{5} x + 6 \end{gathered}$

Looking at the equation above, the slopes are neither perpendicular nor parallel.

Using the definitions of even integer and odd integer, give a proof by contraposition that this statement is true for all intege

kvasek [131]

Suppose $n$ is even, i.e. there is some integer $k$ such that $n=2k$ . Then

$3n-5=3(2k)-5=6k-5=6k-6+1=2(3k-3)+1=2K+1$

where $K$ is just some other integer. Therefore $3n-5$ is odd, proving the contrapositive, and so the original statement is also true.
