Answer:
the third table listed here
Step-by-step explanation:
A "proportional" relationship has the same y/x ratio for all values of x and y.
... first table: all entries but one have y/x = 1/3. The 3rd entry has y/x = 0.4—not the same.
... second table: 6/4 ≠ 8/6
... third table: all entries reduce to y/x = 15
... fourth table: 3/2 ≠ 4/3
2.5 feet is half of 5 feet meaning we know that 2.5 feet is gonna be equal to half of two inches. So we need the answer that gives us one. 2/2.5 = 0.8 and 0.8/5 = 0.4. This means the answer is not A as it is too small. 5/2.5 = 2 and 2/2 = 1 meaning that it must be b. Therefore it cannot be c cause its already b.
Answer:
The equation is,
Step-by-step explanation:
According to the question, the equation is cubic and have roots -1 (with multiplicity of 2) and -2.
So, the equation is,
[Since, when a , b , c are the roots of a cubic equation, the equation is
given by ]
