jonas wants to mail a package that weighs 4.2 kilogram. how much dose the package weigh in pounds?

we know that

1 kg = 2.20462262185 lb

1 kg=2.2 lb

4.2 kg

Convert to pounds

4.2 kg=4.2*(2.2)=9.24 pounds

therefore

Match each as either linear or non-linear. HELP

Virty [35]

Answer:

<u>Linear</u>

y=-x

$y = \frac{x}{9}$

$- \frac{2}{3}x + 3y = 1$

<u>Non linear</u>

$y = \frac{4}{x}$

$\frac{2}{y} = x$

${x}^{2} + {y}^{2} = 1$

Step-by-step explanation:

Linear equations have the highest degree to be 1.

Therefore y=-x is linear.

$y = \frac{x}{9} \: is \: also \: linear.$

$y = \frac{4}{x} \implies \: xy = 4$

The degree of this equation is 2.

It is non-linear

$- \frac{2}{3}x + 3y = 1$

is also linear.

$\frac{2}{y} = x \implies \: xy = 2....non - linear$

${x}^{2} + {y}^{2} = 1.....non - linear$
