Answer: (0, -3/7)
Step-by-step explanation:
The Y-intercept would be the value of y when x is at 0, which is when the Y axis is intercepted. -3/7 is the starting position of the function when the the X = 0.
For this case we have the following conversion:
20 pounds = 9 kilograms
To use the table what we must do is find another relationship that allows us to find the weight in kilograms for 30 pounds.
For example, half the weight in pounds is half the weight in kilograms.
Therefore, the given conversion is:
10 pounds = 4.5 kilograms
So, for 30 pounds, we multiply this last ratio obtained by three on both sides:
30 pounds = 13.5 kilograms
Then, the table is:
Pounds 10 20 30
kilograms
4.5 9 13.5
Answer:
Using the ratio table the dogs weight is:
30 pounds = 13.5 kilograms
Its either 3 or 2
the third way matches only if there's another reference line
I'll go with 3
So we just need to plug in our values and solve
we are given v is 369 so we have
now we solve for x.
divide both sides by 20
square both sides
subtract 273 from both sides
so a temp of about 67 degrees C
