A regular octagon rotates 360° about its center. How many times does the image of the octagon coincide with the preimage during
ycow [4]
Given that the octagon rotates 360 degrees, it is a given that for every regular division of the polygon (360/8 = 45 degrees), the image would coincide with the pre-image during the rotation. Therefore, the octagon would coincide a total of 8 times as it rotates 360 degrees about its center.

Reil [10]

Answer: \boxed{\dfrac{2}{5}}

f(3)

Put the value of x = 3 to the equation of the function

f(x)=\dfrac{4}{5}x-2\\\\f(3)=\dfrac{4}{5}\cdot3-2=\dfrac{4\cdot3}{5}-2=\dfrac{12}{5}-\dfrac{10}{5}=\dfrac{12-10}{5}=\boxed{\dfrac{2}{5}}

Help find the value of x<br> -2(4-x)=12x-3
Mkey [24]

Answer:

Step-by-step explanation:

distributive property

-8 + 2x = 12x - 3

add 3 to both sides

-5 + 2x = 12x

subtract 2x from both sides

-5 = 10x

divide by 10 for both sides

-5/10 = x

-0.5 = x
