Answer:

3/9

Step-by-step explanation:

A repeating decimal is a decimal in which the last number is the same forever. (Ex. .83333333333333333)

So...

2/5 = .4 Not Repeating

-7 = -7 Just a regular integer so nothing can actually repeat

3/9 = .33333 Yes. the 3 is repeating.

11/12 = 0.916666667 Repeated BUT it ends in 7, it doesn't keep continuing.

Hope this helped :)

19. For the following exercises, use the descriptions of each pair of lines given below to find the slopes of Line 1 and Line 2.

Answer:

The given lines are un-related.

Step-by-step explanation:

In the question, two lines are given as line 1 passes through (-8,-55) and (10,89). Whereas, line 2 passes through (9,-44) and (4,-14).

It is required to find the slope of given lines and figure out whether they are perpendicular, parallel or neither.

To solve this question, first find the slope of both lines. Check if their product is equal to -1, then they are perpendicular. If the slopes are equal the lines are parallel.

Step 1 of 2

Find the slope of first line.

$\begin{aligned}&m_{1}=\frac{89-(-55)}{10-(-8)} \\&m_{1}=\frac{144}{18} \\&m_{1}=8\end{aligned}$

Step 2 of 2

Find the slope of first line.

$\begin{aligned}&m_{2}=\frac{-14-(-44)}{4-9} \\&m_{2}=\frac{30}{-5} \\&m_{2}=-6\end{aligned}$

Since, both slopes are neither equal nor reciprocal of each other.

Therefore, the lines are un-related.
