The <u>correct answer</u> is 2.

Explanation:

The Cartesian coordinate system is made up of 2 axes, the x-axis and the y-axis.

Each axis is a number line; the x-axis is a number line that runs horizontally across the graph, and the y-axis is a number line that runs vertically along the graph.

Answer:

Step-by-step explanation:

Cartesian coordinate system also known as rectangular system of coordinates has two number lines mutually perpendicular to each other cutting at the origin.

The horizontal line is called the x axis and the vertical line is called the y axis.

The point of intersection is the origin. The plane is divided into four equal quadrants by these two lines. I quadrant has both x and y positive, II quadrant has (x,y) as (negative, +ve), III quad (-,-) and IV (+,-)

This enables to graph any two dimensional functions as graphs.

Pls help I’ll make brainlest and give extra points

allochka39001 [22]

Answer:

p>-3 open circle going to the right

$m\leq -4$ closed circle going to the left

n<5 open circle going to the left

$h\geq 2$ closed circle going to the right

1>x open circle going to the left

-1=d just a closed circle

Step-by-step explanation:

Before I answer these here are some good notes

If the inequality sign is < or > then the circle is going to be open

If the inequality sign is $\leq or\geq$ then the circle is going to be closed

If the inequality sign is facing the variable (ex: x>3) then the line is going to be going to the right

If the inequality sign is facing the constant (ex: x<3) then the line is going to be going to the left

p>-3 open circle going to the right

$m\leq -4$ closed circle going to the left

n<5 open circle going to the left

$h\geq 2$ closed circle going to the right

1>x open circle going to the left

-1=d just a closed circle

Convert 0.0000.489 to scientific notation

Volgvan

I do not understand why there are two decimal places.
But either ways if you are asking for :
0.0000489 then it is 4.89*10⁻⁵
0.489 then it is 4.89*10⁻¹
The trick is to count the zeroes to the first actual significant number you see and then write the number you counted with a negative sign for your power.
I hope this helps!

Explain why f(x) = x2+4/x2-x-2 is not continuous at x = 2.

xxTIMURxx [149]

Answer: Option a.

Step-by-step explanation:

Make the denominator equal to zero and solve for x:

Factor the quadratic equation. Find two number whose sum is -1 and whose product is -2. Then:

$x^{2}-x-2=0\\(x-2)(x+1)=0\\x=2\\x=-1$

Then, as you can see the value x=2 makes the denominator equal to zero and the division by zero does not exist. Therefore you can conclude that the function shown in the problem is not defined at x=2

The answer is the option a.
