Answer:
use formula
(x,y) =[ (x1+x2)/2 ,(y1+y2/2)]
=[(-2-8)/2, (3-9)/2]
=(-10/2 ,-6/2)
=(-5,-3)
Answer:
63
Step-by-step explanation:
3x^2+5y
Where X=4,Y=3
So
=3×4×4+5×3
=48+15
=63
So 63 is the answer
C= 2(4 + 3)
this might be too complicated but C (Cooper's goldfish) equals 2 times 4 + 3
Answer:
623 is the answer
Step-by-step explanation:
equation : 8X-1
8(1)-1 = 7
8(2)-1 = 15
8(3)-1 = 23
8(4)-1 = 31
8(78)-1 = 623
5 mph to get that answer you use the speed equation
speed(mph)=distance(in miles)/time(in hours)
2.5
------ = 5 mph
.5
