For this case we have a quadratic equation of the form:

Where:

We find the roots:

The roots are:

Answer:

Answer:
The correct option is d


The correct option is d
The correct option is c
the correct option is b
Step-by-step explanation:
The given equation is

The give interval is 
Now differentiating the equation

Therefore the equation is positive at the given interval
Now at x= 1

Now at x= 2

Now at the interval (1,2)

i.e

this tell us that there is a value z within 1,2 and
f(z) = 0
Which implies that there is a root within (1,2) according to the intermediate value theorem
When you turn 90 degrees from north-west you would be in south-west direction. Then, south-east will be in your 90 degrees left.
At first, she had +2y in the upper and -5y in the lower.
She multiplied the upper by 5 . Then she had +10y in the upper.
She should multiply the lower by 2 . Then she'll have -10y
there. She'll be able to add the two equations, and the 'y's will
go away. She'll be left with a single equation with only 'x' in it,
and she can solve that one for the value of 'x'.
The answer i got is 44/3 but as a mixed number it’s 14 2/3
