2,3,5,7,13,15,23,and 61 are all prime
I think its 2 (not sure though just a guess)
Answer:
R(16,-8)
Step-by-step explanation:
if (x1,y1) and (x2,y2) are coordinates of two points and (x,y) the coordinate of midpoint.
then x=(x1+x2)/2
and y=(y1+y2)/2
let coordinates of R are (x,y)
4=(-8+x)/2
8=-8+x
x=8+8=16
-3=(2+y)/2
-6=2+y
y=-6-2=-8
so R is (16,-8)
Step-by-step explanation:
- This is a polynomial, and every expression like y=p(x) , with p(x) a polynomial, is a function.
40% from 25 is:
25 * 40% =
= 25 * 40/100 =
= 25 * 4/10 =
= 25 * 0,4 =
= 10
Another way is to find 1% of 25 and then multiply it by 40:
25 * 40% =
= (25 / 100) * 40 =
= 0,25 * 40 =
= 10
