Answer: C. is the right answer.
Step-by-step explanation:
Given: The cost of a chessboard at Odyssey Gifts is $6.
The function F(x) = 6x gives the cost of x chessboards.
Since x is the number of chessboards, thus the domain of the function should be the set of whole numbers.
Therefore, Domain= {0,1,2,3,4,5,....................}
when we put the values for x from the domain in the function we get values multiples to 6.
therefore range of the function={0,6,12,18,24,30,......}
Hence, C is the right option.
Normallly people want miles per hour or miles/hour
so divvided 420 by 7 =420/7=60/1=60 miles per hour
6x-14+12x+8 that is the answer
As the complete angle is right angle that is 90°
So both the angles should add up to 90°
(3x+2) + (x+16)=90
combine the like terms
4x+18 = 90
Subtract 18 from both sides
4x= 72
divide both sides by 4
x=18
