Hello,
Question 15
We can search x such that:

There is 1 solution.
Question 16
Again, we search x such that:
There are two solutions.
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
Answer:
see explanation
Step-by-step explanation:
y = 1 is the equation of a horizontal line parallel to the x- axis.
Since it is parallel to the x- axis then its slope is zero.
A line perpendicular to it will therefore be a vertical line parallel to the y- axis.
The slope of the perpendicular line is undefined.
The slope of a parallel line is zero
- Relationship between the variables are
- (a) As the age increases, the height increases.
- No relationship between variables.
- (a) As the age increases, height decreases.
- (b) As the height decreases, the age decreases.
Step-by-step explanation:
- If visually found a child born till his age of elder he has increased.
- It is clearly true that as the age increases height increases.
- Child is born at some point of time with a particular height.
- It is never an association between age increases and height reduces.
- Age is again started at some point of time, it cannot decrease.
- After descriptive statistics there something called predictive.
- Describing the data is one way of understanding statistics.
- It is mean,median mode where the particularly number stands.
- Predictive is the next stage an association of variables.
- Variables are very important in analysis it basically attribution.
- In order to find any analyse test studies are important variables to.
Answer:
Option B.
Step-by-step explanation:
If a quadratic equation is defined as
.... (1)
then the quadratic formula is

The given equation is

It can rewritten as
.... (2)
On comparing (1) and (2) we get

Using quadratic formula we get



Therefore, the correct option is B.
