Answer:
A
Step-by-step explanation:
Recall that for a function to be valid, each input value of x must give us one and only one unique output value for y.
in this case we can see that one of the data sets is (3,-1)
which means that an input of 3 gave an output of -1
but we also see that another data set (3,1)
in this case an input of 3 gave an output of 1.
Because the same x input gives 2 different y outputs, this is not a function.
the answer is A
Answer:
Octagon
Step-by-step explanation:
Formula for a polygon is :
- a = apothem (distance from center to the midpoint of a side
- P = perimeter (sum length of the sides)
Since a regular octagon has 8 sides, and a regular hexagon has 6, the octagon will have the greater area due to greater perimeter.
3/2+y/3=2
3/2+y=2.3
3/2+y=6
3/2-6=-y
3-12/2=-y
-9/2=-y
-9/-2=y
9/2=y
4.5=y
