Answer:
The relation y=2x+8 is a function because the two different output values of the function have the one unique input value.
Step-by-step explanation:
The given relation is y=2x+8.
It is required to determine the relation is a function.
This solution can be obtained by using the concept of function. First write the given relation y=2x+8 and determine whether the given relation is a function.
Step 1 of 1
The given relation is y=2x+8.
This relation shows that the two different output values of the function have one unique input value and this relation is a linear function.
Hence, the relation is a function.
The square root of 144 is 12
Answer: -2.6%
Step-by-step explanation:
Percent error is the difference between the measured and known value, and then we divide by the known value, and then multiply by 100%.
Estimated.number = 15.4 grams.
Actual number = 15.8 grams
Percentage error = (Estimated number - Actual number)/Actual number × 100
= (15.4 - 15.8)/15.8 × 100
= -0.4/15.8 × 100
= 0.0253 × 100
= 2.53
= -2.6% approximately
Answer:
x = 
Step-by-step explanation:
Using the Pythagorean Theorem we can solve this problem.
The legs of the triangle will be the same (the dashes in the middle of the line indicates they are the same).
The Pythagorean Theorem will look like this:
Now, let's find a:
The square of a radical will be whatever is under the arch
Divide 11 by 2
Square root both sides
a =
Therefore, the length of side x is equal to .
