Answer:
The answer to the first question is : y = 7 (10s - 10)
The answer to the second question is : I think C
The answer to the third question is : "B or D"
The answer to the fourth questions is : ( I don't understand the last question)
Step-by-step explanation:
B for sure!!!!!!!!!!!!!!!!!!!
Mark would have ran 6 miles if he ran 9.654 kilometers
Answer:
Yes number 5 is, they are proportional because y is coresponding to x by multiplying by 1/5
No number 6 isn't, you can't go from 3 to 1 and 7 to 3
Answer:
You can tell that quantities x and y are proportional if they are effecting each other.
Step-by-step explanation:
If two quantities are proportional that means they are dependent on each other.
- The quantities can be directly proportional and inversely proportional as well.
- If the increase in one quantity will increase the other quantity and decrease in quantity leads to the decrease in other then it is directly proportional. Like in Ohm's Law: the current and voltage are directly proportional in linear circuit while neglecting the resistance. The following expression show this direct proportional relation:
V ∝ I
- If the increase in one quantity results in the decrease of the other quantity or vice versa then these quantities are inversely proportional. Like if the people required to do a job increases then time required to complete the job will decrease or vice versa.
