Y= 5x - 9; domain = { 1,3,7 }<br> what is the range values?
Maslowich

Answer:

Step-by-step explanation:

range = [-4,6,26]

Step-by-step explanation:

y = 5x - 9.....domain = [1,3,7]....the domain is ur x values, and I am assuming ur looking for the y values that go with the x ones

y = 5x - 9.....when ur domain (ur x) = 1

y = 5(1) - 9

y = 5 - 9

y = -4

y = 5x - 9...when ur domain (x) = 3

y = 5(3) - 9

y = 15 - 9

y = 6

y = 5x - 9...when ur domain(x) is 7

y = 5(7) - 9

y = 35 - 9

y = 26

so ur range (ur y valus) = [-4,6,26]

Geometry help? How would I solve this?
Firlakuza [10]
\bf \textit{sum of interior angles in a regular polygon}&#10;\\\\\\&#10;n\theta=180(n-2)\qquad &#10;\begin{cases}&#10;n=\textit{number of sides}\\&#10;\theta=\textit{angle in degrees}&#10;\end{cases}&#10;\\\\\\&#10;\textit{notice, your two polygons, are just two regular octagons}\\&#10;\textit{OCTAgons, thus OCTA = 8, 8 sides, thus}&#10;\\\\\\&#10;n\theta=180(n-2)\qquad n=8\implies 8\theta=180(8-2)&#10;\\\\\\&#10;\theta=\cfrac{180\cdot 6}{8}

so... that's how much an internal angle is
now, subtract that from 180 and you get the angle outside, in the picture

subtract that outside angle twice from 180, and you get angle "2"
because angle 2 is in the same triangle as those two outside angles, and all internal angles in a triangle is 180, thus 180 - (those two angles) is angle "2"
