When you're subtracting fractions you turn them into improper fractions. When you're adding fractions you just change the denominator so they're the same, or turn them into improper fractions.
3x-6 = 7x +1
7x-3x= -(6+1)
4x=-7
x= -7/4
Acute has an angle under 90 degrees while Obtuse has an angle OVER 90 degrees. A triangle has to have three sides that equal up to 36 degrees,
Simple.
Based on the table, the equation of the line of best fit to the nearest thousandths is equal to y = 1.671x + 4.699.
<h3>How to determine the equation of the line of best fit?</h3>
Mathematically, the equation of the line of best fit is calculated by using this formula:
y = mx + c
<u>Where:</u>
Based on the table, the slope and intercept to the nearest thousandths are equal to 1.671 and 4.699 respectively.
Therefore, the equation of the line of best fit is equal to y = 1.671x + 4.699.
