Question

Explain the similarities between rational numbers and rational expressions ?

hintHint:

Both rational numbers and expressions are written in fraction form.
We are asked to find the similarities between rational expression and rational numbers.

The correct answer is: But both rational numbers and expressions are written in fractional form containing both the numerator and the denominator.


    Step 1 of 1:
    Rational numbers are of the form, p over q, q not equal to 0. Here both  straight p straight & straight qare numeric values.
    Eg comma 2 over 3
    In case of rational expressions, they are again in a p over q comma q not equal to 0 form but both straight p straight & straight q are polynomial expressions.
    text  Eg, end text fraction numerator 2 x plus y over denominator 3 y end fraction
    But both rational numbers and expressions are written in fractional form containing both the numerator and the denominator.

    When we find the domain, we should exclude the values for which the denominator attains a zero.

    Write the equation in slope-intercept form of the line that passes through the points (5, 4) and (-1, 6).

    The slope intercept form is y = mx + b, where m represents the slope and b represents the y-intercept. We can draw the graph of a linear equation on the x-y coordinate plane using this form of a linear equation.
    Steps for determining a line's equation from two points:
    Step 1: The slope formula used to calculate the slope.
    Step 2: To determine the y-intercept, use the slope and one of the points (b).
    Step 3: Once you know the values for m and b, we can plug them into the slope-intercept form of a line, i.e., (y = mx + b), to obtain the line's equation.
