A would either be + or -3, or + or minus 4 depending on what b is
3+4+1 for each class so it's 8
8 x 6 for all the classrooms so it's 48. The school buys 48 games
Answer:
D(9, 1)
Step-by-step explanation:
A being the midpoint means its coordinates satisfy ...
A = (E + D)/2
Solving for D, we find ...
D = 2A -E
= 2(4, 5) -(-1, 9) = (2·4 +1, 2·5 -9)
D = (9, 1)
