Answer:

Undefined

Step-by-step explanation:

$y=-7$ has a slope of $0$ , since it is a horizontal line. The only types of lines that are perpendicular to horizontal lines are vertical lines, which are usually in the form $x=a$ (where $a$ is any real number). Vertical lines have an undefined slope, so the answer is undefined. Hope this helps!

Complete the sequence of numbers in the set. Explain the pattern.The completed sequence of numbers is 8.5, 7.15, 5.8,

Mademuasel [1]

Answer:

$8.5,7.15,5.8,4.45,3.1,...$

Step-by-step explanation:

The first step to solve this question is to analyze the given sequence.

We can notice that the difference between 8.5 and 7.15 is

$8.5-7.15=1.35$

And again the difference between the second and the third term is :

$7.15-5.8=1.35$

One way to describe all the numbers in the sequence is by using a formula.

We can write :

Given the sequence $a_{0},a_{1},a_{2},a_{3},...$

$a_{n}=8.5-(1.35)n$ with $n$ ∈ I $N_{0}$

For example :

$a_{2}=8.5-(1.35).2=5.8$ which verifies our original sequence.

We can obtain any term we want of the sequence.

Some of the terms that complete the sequence are :

$8.5,7.15,5.8,4.45,3.1,...$
