Only 25 and 28 are functions.
A function must have only one y value per x value. For 26, the y value of 0 and multiple others have two different y values. For 27, all x values less than 0 have multiple y values.
144 x 3= (D) 432
Hope this can help! :)
Answer:
I think it is E and C
Step-by-step explanation:
E) y - 6 = -7/4(x+5)
(-5,6)
6-6=-7/4(0)
0=0
(-1,-1)
-1-6=-7/4(-1+5)
-7=-7/4(4)
-7=-7
We know that the Circumcenter is the intersection of a triangle's right (perpendicular) bisectors. Once you have found two of these you can determine their point of intersection.
It is a proven mathematical concept that the third perpendicular bisector will also cross through this intersection point. While it is not necessary to construct all three it is often done so to verify that the intersection of the first two perpendicular bisectors was in fact correct.
Answer:
2:5
Step-by-step explanation:
Because if we look 8:20 can be turned into 8/20 and if we simply we got 2/5 and turn it into 2:5
