Answer:
k < -5
Step-by-step explanation:
5(k+4)<–5
Divide each side by 5
5/5(k+4)<–5/5
k+4 < -1
Subtract 4 from each side
k+4-4 < -1-4
k < -5
There is no such thing as a "kilowatt per hour". If that's actually what the question says, then it's a defective question, and you should put it away before it makes you any more confused.
A 120 watt light bulb uses exactly 0.12 kilowatt when it's turned on.
In one hour, it uses
(0.12 kilowatt) x (1 hour) = 0.12 kilowatt-hour of energy.
If energy costs $0.20 per kilowatt-hour, then the cost is
(0.12) x (0.20) = 2.4 cents. (0.024 dollar)
Answer:
7x+3=2x-6 #4
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>Reading rate is y pages per x minutes and proportional relationship formula is:</u>
<u>The coefficient is:</u>
<u>Let's verify if the given numbers fit into the same relationship:</u>
- 12/18 = 2/3
- 8/12 = 2/3
- 20/30 = 2/3
We confirm all same and it means k = 2/3
<u>Required equation is:</u>
This represents that Michael reads 2 pages per 3 minutes and for x minutes he reads 2/3x pages
Answer:
The easiest way to do this is to reflect Figure I over the Y axis. Then move it up 3 and left 2.
