For f(x) = 24-2x, find f(2) and find x such that f(x) =10

Svetradugi [14.3K]

f(x) = 24 - 2x

f(2) This means that x is 2, so you can plug in 2 for x

f(x) = 24 - 2x

f(2) = 24 - 2(2)

f(2) = 24 - 4

f(2) = 20

To find x when f(x) = 10, you can do:

f(x) = 24 - 2x [substitute/plug in 10 for f(x)]

10 = 24 - 2x Subtract 24 on both sides

-14 = -2x Divide -2 on both sides

7 = x

The exterior angle of a regular polygon is 30°. What is the measure of an interior angle of the polygon.

astraxan [27]

Answer:

A) Measure of an interior angle of polygon = 150°

B) No of sides = 12

C) Sum of all interior angles = 1800°

Step-by-step explanation:

Measure of interior angle of polygon = 180°- measure of exterior angle of polygon

= 180°-30°

= 150°

$No.\: of \: sides = \frac{360\degree}{30\degree} = 12\\\\C.\\Sum\:of\: all \:interior\: angles \\= (n-2)\times 180\degree\\= (12-2) \times 180\degree\\= 10\times 180\degree\\= 1800\degree$
