Answer:
The discriminant of the quadratic equation is -7.
Step-by-step explanation:
We are given the following quadratic equation in the question:
Comparing to general quadratic equation:
We have to find the discriminant of the quadratic equation.
Formula:
Putting values, we get,
Thus, the discriminant of the quadratic equation is -7.
He drove 56 miles because if you divide 168 and 3 it equals 56.
Answer:
infinite
Step-by-step explanation:
If you multiply all factors in the secon eqation by 4, you will get the first eqation.
Therefore for any value of x you can find y, thus having an infinite number of x,y pairs
Answer:
Step-by-step explanation:
we know that
The roots of the polynomial are the values of x when the value of the polynomial f(x) is equal to zero
The roots of the polynomial function are
x=-6 -----> (x+6)=0
x=-5 -----> (x+5)=0
x=-1 -----> (x+1)=0
The equation of the cubic polynomial is
where
a is the leading coefficient
Remember that
f(0)=60
That means ------> For x=0 the value of f(x) is equal to 60
substitute the value of x and the value of y in the function and solve for a
so
Applying the distributive property
Convert to expanded form
Since the denominators are the same, just subtract the numerators.
The answer is 3/10.
