Answer: The required number of ninths needed is 3.
Step-by-step explanation: We are given to find the number of ninths that will after combining together make the amount as
Let, 'n' be the required number of ninths.
Then, according to the given information, we have
Therefore, required number of ninth needed is 3.
Thus, the answer is 3.
Answer:
Step-by-step explanation:
If we simplify that fraction, we get
Keep that in mind.
If y, a ,b are zeroes of the cubic polynomial, then that means
make up the polynomial.
Notice that leading xoeffeicent will be 1, so the roots will multiply to
so
which gives us
Proof:
Consider the function
The roots are 2, 3, 5.
D is -30 so we get
Using the value,
If we use the orginal equation, we get
Answer:
A
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (- 3, 4 ) and (x₂, y₂ ) = (2, - 1 )
m = =
=
= - 1 → A
