m = -36
Answer:
36.5 inches
Step-by-step explanation:
Given
See attachment for the given data
Required
Which length is closest to 4.2lb
The given data is a linear dataset.
So, we start by calculating the slope (m)
Pick any two corresponding points from the table
So, we have:
So:
The linear equation is then calculated using:
This gives:
Open bracket
To get the length closest to 4.2lb,
we set
Then solve for x
So, we have:
Collect like terms
Solve for x

Answer:
x = ±
Step-by-step explanation:
Given
2x² - 9 = 11 ( add 9 to both sides )
2x² = 20 ( divide both sides by 2 )
x² = 10 ( take the square root of both sides )
x = ± ← exact solutions
