Solve the following inequality algebraically.<br><br> ∣x+7∣≤8
AlekseyPX

Answer:

x ≤ 1 and x ≥ −15

Step-by-step explanation:

<u>Solving Absolute Value</u>

  • We know that x + 7 ≤ 8 or x + 7 ≥ -8

<u>Condition 1:</u>

Step 1: Subtract 7 from both sides.

  • x + 7 - 7\leq 8 - 7
  • x\leq 1

<u>Condition 2:</u>

Step 1: Subtract 7 from both sides.

  • x + 7 - 7\geq -8 - 7
  • x\geq -15

Therefore, the answer is x ≤ 1 and x ≥ -15.

Dennis_Churaev [7]

Answer:

D(h) = 55h - 2000

1670 m

Step-by-step explanation:

Given :

Starting elevation, D = - 2000 m (2000 m below sea level)

Rate, h = 55 m per hour.

The slope - intercept relation :

y = mx + c

m = slope = rate of change

c = intercept

In the scenario given :

-2000 = intercept

55 = rate of change

D(h) = 55h - 2000

After 6 hours :

D(6) = 55(6) - 2000

D(6) = - 1670 m

VMariaS [17]

Answer:

Option B

same-side interior angles

Step-by-step explanation:

Given in the question, two non parallel lines a and b.

The area between lines a and b is called the interior of the two lines.

Angles 4 and 5 are same-side interior angles.

Other options are wrong because:

<h3>A)</h3>

The area which not between lines a and b is called the exterior

<h3>C) </h3>

Corresponding angles are on same side of the traversal line.

Example

Angles 1 and 5

<h3>D)</h3>

Alternate interior angles are in interior region but in opposite side of traversal line.

Example

Angles 3 and 5
