You can pick 4 and -4. Absolute value is the distance from 0 on a number line. So if I have a 2 on the number line, the amount of space from the 0 is 2. If I have a negative 9 on a number line then the absolute value is positive 9. A absolute value is always positive, even if the number is negative. Hope this helps!

Answer:

4 and -4

Step-by-step explanation:

absolute value is always going to be positive and the overall value will only change if it is negative. so the "|4|" (absolute value of 4) is the same as "|-4|" (absolute value of negative 4)

The perimeter of a triangle is 45 centimeters. find the lengths of its sides if the longest side is 7 centimeters longer than th
dangina [55]
X = length of shortest side
Therefore the remaining sides will be x +2 and x + 7

x + x + 2 + x +7 = 45
3x + 9 = 45
3x = 36
x = 12
x + 2 = 14
x + 7 = 19

The sides are 12, 14, and 19 cm. long. Hope this helped!

In order for a gear to work in a piece of machinery, the radius of the gear, r, must be greater than 4 cm, but not exceed 4.1 cm
sveta [45]

The compound inequality represents the situation is r > 4 and r ≤ 4.1

<h3>Compound inequality</h3><h3 />
  • Radius of the gear = r

  • r must be greater than 4 cm

r > 4

  • r must not exceed 4.1 cm

r ≤ 4.1

Therefore, r > 4 and r ≤ 4.1 is the compound inequality which represent the situation.

A college administration has conducted a study of 224 randomly selected students to determine the relationship between satisfact
leonid [27]
The probability that a student is not on probation is (224 - 79)/224 = 145/224.
The probability that a student who is not on probation is not satisfied with advisement is 21/145.
The required probability is therefore given by:
\frac{145}{224}\times\frac{21}{145}=\frac{3}{32}
The answer is 3/32.

In the figure above, AB is tangent to the circle with center o at point A.
Inessa [10]

<u>Given</u>:

Given that O is the center of the circle.

AB is tangent to the circle.

The measure of ∠AOB is 68° and we know that the tangent meets the circle at 90°

We need to determine the measure of ∠ABO.

<u>Measure of ∠ABO:</u>

The measure of ∠ABO can be determined using the triangle sum property.

Applying the property, we have;

\angle ABO+\angle BAO+\angle AOB=180^{\circ}

Substituting the values, we get;

\angle ABO+90^{\circ}+68^{\circ}=180^{\circ}

Simplifying, we get;

\angle ABO+158^{\circ}=180^{\circ}

          \angle ABO=22^{\circ}

Thus, the measure of ∠ABO is 22°
