1 answer:
Yuki888 [10]3 years ago
6 0

Answer:

true for all x

Step-by-step explanation:

3x - 4 ≤ 2

Add 4 to each side

3x - 4+4 ≤ 2+4

3x<6

Divide by 3

3x/3 <6/3

x<2

or

2x + 11 ≥ -1

Subtract 11 from each side

2x + 11-11 ≥ -1-11

2x≥ -12

Divide by 2

2x/2 ≥ -12/2

x  ≥ -6

x<2  or x  ≥ -6

true for all x

Light travels 1.08 x 10 9 kilometers in one hour. How far does it travel in 2 hours?
ozzi

The distance traveled by the light in 2 hours is 2.16×10⁹ km.

<h3 /><h3>Distance:</h3>

This is the total length of space between two points covered by an object. Distance has no regard for direction as it is termed a scalar quantity. The S.I unit of distance is meter(m).

To calculate the distance traveled by the light in 2 hours, first, we need to calculate the speed of the light.

Formula:

  • S = d/t................. equation 1

Where:

  • S = speed
  • d = distance travelled
  • t = time

From the question,

Given:

  • d = 1.08×10⁹ km
  • t = 1 hour

Therefore,

  • s = 1.08×10⁹/1
  • s = 1.08×10⁹ km/h

The distance traveled in 2 hours is

  • d = 2×1.08×10⁹
  • d = 2.16×10⁹ km

Hence, the distance traveled by the light in 2 hours is 2.16×10⁹ km

Aliun [14]
Corrine earns an hourly wage on top of her weekly gas allowance for her delivery job.

Her weekly earnings can be expressed as:

Earnings = 40 + 7.50h

When h=0, her earnings will be 40

This constant represents, the fixed gas allowance she is receiving for her delivery job. 7.50h represents that she get paid $7.50 for an hour of work. 

So, the constant term in the expression represent her weekly gas allowance.
