Answer:
predicted: 15.7
residual: 1.3
Step-by-step explanation:
In x-axis, age of the tree is represented, and in y-axis, height of the tree is represented. When the tree is 5 years, x = 5, and the predicted value is:
f(5) = 1.3(5) + 9.2 = 15.7
Residual value is computed as follows:
residual = observed - predicted
residual = 17 - 15.7 = 1.3
(3x² + 5xy - 2y²)
3x² + 5xy - 2y² <em>(rewrite the expression) (write 5xy as a difference)</em>
3x² + 6xy - xy - 2y² <em>(factor the expression) (factor out 2x from the expression)</em>
3x x (x + 2y) -y x (x + 2y) <em>(factor the expression) (factor out x + 2y from the expression)</em>
<em>Solution</em> : (x + 2y) x (3x - y)
