Answer:

y\in(-\infty ,-3)\cup(7,\infty )

Step-by-step explanation:

We have been given the compound inequality

y -2 < -5 or y -2 > 5

Since 2 is in subtraction with y hence in order to eliminate it we can do the reverse operation of subtraction which is addition.

Hence, add 2 to both sides

y -2+2 < -5+2 or y -2+2 > 5+2

y < -3 or y > 7

In interval notation, we have

y\in(-\infty ,-3)\cup(7,\infty )

The graph has been shown in the attached file.

Devin is collecting signatures for a petition to open a new park in her town. She needs to collect at least 1,000 signatures bef
steposvetlana [31]

Answer:

The correct opion is;

7 ≤ p

Step-by-step explanation:

The number of signatures Devin needs to collect = 1,000 signatures

The numer of signatures Devin has already = 380 signatures

The number ofsignatures each petition page can hold = 80 signatures

Therefore;

The number of extra signatures required = 1,000 - 380 = 680 signatures

The number of petition pages required = 1,000 petitions /(80 signatures/page)   = 12.5 pages

The number of pages already filled = 380 petitions /(80 signatures/page) = 4.75 pages

The number of pages remaining, p = 12.5 - 4.75 = 7.75 pages

Therefore, 7 ≤ p.

Find the LCM of 12 and 18
Ipatiy [6.2K]

Answer: 36

Step-by-step explanation: To find the least common multiple or <em>lcm</em> of 12 and 18, begin by listing the first few multiples of each number.

<em>Multiples of 12</em>

1 × 12 = 12

2 × 12 = 24

3 × 12 = 36

Notice that we skipped 0 × 12 in our list of multiples. That's because 0 × 6 is 0 and our least common multiple can not be 0.

When listing the multiples of 18, it's a good idea to keep an eye on the list of multiples for 12 so that we will notice when we find a least common multiple.

<em>Multiples of 18</em>

1 × 18 = 18 ← is not multiple of 12

2 × 18 = 36 ← is a multiple of 12

Notice that we can stop here because all other multiples that we find will be greater 36. So the least common multiple of 12 and 18 is 36.
