What is the equation of the linear function represented by the table?
Korolek [52]
Hello!

You can put x into the answer choices to see if we get y
----------------------------------------------------------------------------------------------------
y = -x + 9
y = -(-5) + 9
y = 5 + 9
y = 14

This could be a answer

y = -(-2) + 9
y = 2 + 9
y = 11

y = -(1) + 9
y = -1 + 9
y = 8

y = -(4) + 9
y = -4 + 9
y = 5

we got y every time so the answer is the first one

The answer is A) y = -x + 9

Hope this helps!

The percentage of water in an unknown hydrate was determined by heating the sample and driving the water off the sample. Two ind
Bas_tet [7]

Answer:

It should be reported as 20.648%

Step-by-step explanation:

Since we have 2 different observed values hence we shall use an average of the 2 values to report the result

Thus value is \frac{19.564+21.731}{2}=20.6475%

As we can see that the least count of our observations is upto 3 decimal places hence we have to report a result upto only 3 decimal places thus we need to round off the fourth decimal place thus the digit shall be increased by 1 since we have to drop off 5 and the digit before 5 is 7 which is an odd number.

Thus the result shall be 20.648%
