Ответ:
Rational numbers are numbers that can be written as the fraction of two integers. To multiply rational numbers together, you multiply the tops and bottoms separately to get your answer.
Step-by-step explanation:
Ответ:
x^2+y=4 and -y-1 are not linear equations.
Step-by-step explanation:
The exponent in x^2 indicates this is a polynomial equatuon, because when graphed, it doesn't form a line.
In -y-1, there is no given x value. y is an output of a solved x equation, so without an x, it cannot be completed. Equations depend on a number that can be plugged in. When graphed, it appears as an error.
-x-y=2 is linear because it can be rearranged to solve for y and can be graphed as linear.
x=5 is linear because it gives an input value, and shows that the output value when solved is 0 (no y means it will always be 0). When graphed, it shows a straight line, which is linear.
