Answer:
If it cuts x-axis 5 times.
Step-by-step explanation:
When we look at the graph of a function we can see its real roots by looking at its graph
The intersecting points that is the number of times a line cutting x-axis will be the real root of the function
So, by looking at the 5th degree function the number of time that function cuts x-axis will be the number of real roots.
So, if we need to say all the zeroes or roots of the function are real means it will cut the x-axis 5 times.
Because a function will have the root equal to its degree.
False a rectangle could never be a square
Answer:

Step-by-step explanation:
The slope of this line is 2 because the rise from one point is 2, and the run is 1. The change in y-value is divided by the change in the x-value which is 2/1, hence, the slope of the line being 2.
The slope of the line perpendicular to the one shown below will be
because the slope that will result in a perpendicular line is the negative reciprocal of the original slope.
Answer: 
Each term is half of the previous one, so the common ratio is 1/2. Then to get from the first term to the nth term, you have to take n - 1 steps, multiplying by 1/2 each time and by 6000 to account for the first term.
i hope this helps! :D
we have

we know that
If the point is an equation solution, it must satisfy the equation.
<u>case a</u>) 
Substitute the values of x and y in the equation


-------> the point is not solution of the equation
<u>case b</u>) 
Substitute the values of x and y in the equation


-------> the point is solution of the equation
<u>case c</u>) 
Substitute the values of x and y in the equation


-------> the point is not solution of the equation
<u>case d</u>) 
Substitute the values of x and y in the equation

-------> the point is not solution of the equation
therefore
<u>the answer is</u>
The point
is solution of the equation
