The answer to that question is 4
9y(8y² - 2y + 4)
9y(8y²) - 9y(2y) + 9y(4)
72y³ - 18y² + 36y
The idea is to find a linear combination a_1(5, -6) + a_2(-2, -2) = (-6, 2)
It boils down to a system of equations:
Take the augmented matrix:
<span>[<span><span>5<span>−6</span></span><span><span>−2</span><span>−2</span></span><span><span>−6</span>2</span></span>]</span>
Reduced form:
<span>[<span><span>10</span><span>01</span><span><span>−<span>811</span></span><span>1311</span></span></span>]</span>
-(8/11)*(5, -6) + (13/11)*(-2, -2) = (-6, 2)
105 Animals....You know that because when you add together the head & feet that's adding all the animals together to get the total number of animals
Answer:
In the model, you can see that it is split up into four parts. It also shows that the whole model is 2/3. So, an equation you could write is
