Answer:</h3>
y = x⁴ +4x³ +4x² +4x +3
<h3>
Step-by-step explanation:</h3>
The coefficients of the offered quartics (in order) have 1, 1, 1, and 0 sign changes, respectively. Descartes' rule of signs tells you this means the first three choices all have one (1) positive real root, so the negative real roots -1 and -3 are not the only ones.
The only possible polynomial is the last one. Synthetic division of that polynomial by roots -1 and -3 leave the remaining factor as x²+1, which has only complex zeros.
The appropriate choice is ...
... y = x⁴ +4x³ +4x² +4x +3
Answer:
Cost of each pound of Soybean is $10 and each pound of wheat is $2.
Step-by-step explanation:
Let the Cost of each pound of soybeans be 'x'.
Also let Cost of each pound of wheat be 'y'.
Now Given:
each pound of soybeans cost five times as much as each pound of wheat.
so equation can be framed as;
⇒ Equation 1
Now Given:
Amount of soybean = 4.7 lb
Amount of wheat = 2.4 lb
Total Cost = $51.80
Now we can say that;
Total Cost is equal to sum of Amount of soybean multiplied by Cost of each pound of soybeans and Amount of wheat multiplied by Cost of each pound of wheat.
framing in equation form we get;
⇒ Equation 2
Now Substituting equation 1 in equation 2 we get;
Now Dividing both side by 25.9 we get;
Now Substituting the value of y in equation 1 we get;
Hence Cost of each pound of Soybean is $10 and each pound of wheat is $2.
