This depends on the inequality sign is compared to the y variable

For example, if the inequality is y < x, you would shade under the line x

If the inequality is y > x, you would shade above the line x.

The pair of numbers whose difference is 18 and whose product is as small as possible is? The minimum product is?

earnstyle [38]

Assume the bigger number is x, since the difference is 18, another one should be x - 18

So the product will be x(x-18) = x^2 - 18x = (x-9)^2 - 81

Since the minimum of (x-9)^2 is 0, then the minimum of the product is -81

If a wave has a wavelength of 0.5 m and a frequency of 2134 Hz, what is its speed? *SHOW ALL 4 STEPS.

nexus9112 [7]

<h3>given:</h3>

wave length= 0.5 m

frequency= 2134 Hz

the speed

<h3>solution:</h3>

$v = f \gamma$

$v = velocity$

$f = frequency$

$\gamma = wave \: length$

$v = 2134 \times 0.5$

$v = 1067s$

hence, the speed of the wave is 1067s.

The answer is 15/18
because if you just put 15/18 it will give you 0.83333333333
and for 2/3 it will give you 0.66666666666
and we all know which number is bigger.
Hope this helps
