6 0

Answer:

An equation is linear if its graph forms a straight line. This will happen when the highest power of x is "1". Graphically, if the equation gives you a straight line then it is a linear equation. Else if it gives you a circle, or parabola or any other conic for that matter it is a quadratic or nonlinear equation.

name three different pairs of fractions that have the same product when multiplied .explain how you got your answer

Deffense [45]

$\frac{5}{10}*\frac{10}{40}=\frac{50}{400}$
$\frac{2}{8}*\frac{2}{4}=\frac{4}{32}$
$\frac{1}{4}*\frac{1}{2}=\frac{1}{8}$

$\frac{1}{8}$ is obtained by multiplying $\frac{1}{2}$ and $\frac{1}{4}$
You basically create equivelant fractions for both 1/2 and 1/4 and multiply by each other. This way you get the same result always.
