Step-by-step explanation:
I think this would be correct? haha
y2-y1/x2-x1
6-4=2,3--2(or 3+2 because 2 negatives make a positive)=5, so 2/5.
I hope this helps :)
What do you mean by without calculating?
Center at (h,k) and radius r is
(x-h)²+(y-k)²=r²
so given
center at (9,-8)
(x-9)²+(y-(-8))²=r²
(x-9)²+(y+8)²=r²
input the point (19,22) to find r²
x=19 and y=22
(19-9)²+(22+8)²=r²
10²+30²=r²
100+900=r²
1000=r²
10√10=r
well, the equation is
(x-9)²+(y+8)²=1000
Answer:
[8 -6 2 -4].
Step-by-step explanation:
[4 -4 0 0]+[4 -2 2 -4]
= [4+4 -4+-2 0+2 0+-4]
= [8 -6 2 -4]
There are 7 days in a week.
1/2 hour x 7 days = 3 1/2 hours per week.
3 1/2 hours per week x 4 weeks = 14 hours
