Answer:
(9, 6)
Step-by-step explanation:
<u>Midpoint formula is:</u>
- x = (x₁ + x₂)/2
- y = (y₁ + y₂)/2
<u>Having coordinates of one end- and midpoint </u>(-5, 12) <u>and</u> (2, 9)<u>:</u>
- x₁ = -5, y₁ = 12
- x = 2, y = 9
<u>we get the coordinates of the missing endpoint with coordinates</u> (x₂, y₂):
- x₂ = 2x - x₁ = 2*2 - (-5) = 4 + 5 = 9
- y₂ = 2y - y₁ = 2*9 - 12 = 18 - 12 = 6
<u>So the missing point is</u>: (9, 6)
Answer:
Advanced tickets=30 Day =20
Step-by-step explanation:
Put them into equations:
x=advanced
y=day
x+y=50
25x+15y=1050
to make it simpler re-arrange x+y=50
x=50-y
Then substitute into 25x+15y=1050
25(50-y)+15y=1050
Expand
1250-25y+15y=1050
Rearrange
25y-15y=1250-1050
Work the above out
10y=200
y=20
and then
20+x=50
meaning....
x=30
showing Advanced tickets=30 Day =20
Answer:
A is A=2(1+2)a2
B is A≈208.18cm²
Step-by-step explanation:
A explanation is A=2(1+2)a2=2·(1+2)·102≈482.84271
B explanation is A=145(5+25)a2=14·5·(5+2·5)·112≈208.17777cm²
