Answer:

B) The y-coordinate is 0

Step-by-step explanation:

We are given that,

'In an x-y plane, the x-axis consists of all the ordered pairs of the form (x,y)'.

It is required to find the condition on the ordered pairs.

Since, we know that,

On the x-axis, the value of y= 0.

So, 'x-axis contains the ordered pairs of the form (x,0)'.

Thus, option B is correct.

Answer:

Option B

y coordinate is 0

Step-by-step explanation:

We have in two dimension rectangular system of coordinates with two mutually perpendicular lines called x and y axis.

X axis is the horizontal line and y the vertical line, the point of intersection of these two lines is called origin with x=0: y=0

To the right of origin, positive values are marked and left negative. Similarly for y axis, above origin positive values and below negative values.

Thus we have along x axis, y values to be 0

Hence any point on x coordinate will be of the form (a,0) where a can be any real number

So option B is right

In which of the following ways are linear systems similar to quadratic systems? Select all that apply.
alex41 [277]

The <em>correct answers</em> are:


A) Both can be solved by graphing;

C) Both can be solved by substitution; and

D) Both have solutions at the points of intersection.


Explanation:


Just as a system of linear equations can be solved by graphing, a system of quadratic equations can as well. We graph both equations. We then look for the intersection points of the graphs; these intersection points will be the solutions to the system.


We can also solve the system by substitution. If we can get one variable isolated, we can substitute this into the other equation to solve.

Which expression is equivalent to
Kruka [31]

Answer:

B) 1/x^2

Step-by-step explanation:

Simplify the following:

x^9/x^11

Hint: | For all exponents, a^n/a^m = a^(n - m). Apply this to x^9/x^11.

Combine powers. x^9/x^11 = x^(9 - 11):

x^(9 - 11)

Hint: | Evaluate 9 - 11.

9 - 11 = -2:

Answer:  x^(-2) = 1/(x^2)

Which graph represents the function f(x)=
zhenek [66]

Step-by-step explanation:

you don't show us the choices.

anyway, the real graph must be similar to the one you are showing, as it goes to - and + infinity for x = 2.

because the denominator "x-2" will be 0 for x = 2.

but the horizontal limits are both y = +3 (and not 0).

because (3x-2)/(x-2) goes more and more to 3/1 the larger (or smaller in the - direction) x gets.
