It looks like you have
Substituting these in to the plane equation, we have
When 
, we get the point
10^2+8^2-7^2/(2*10*8)
= 115/160 = 0.71875 round off to 0.72
Answer:
B
Step-by-step explanation:
Given the 2 equations
- 2x = 4y + 6 → (1)
2(2y + 3) = 3x - 5 → (2)
Distribute left side of (2)
4y + 6 = 3x - 5 → (2)
Substitute 4y + 6 = - 2x into (2)
- 2x = 3x - 5 ( subtract 3x from both sides )
- 5x = - 5 ( divide both sides by - 5 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for y
Substituting into (1)
- 2(1) = 4y + 6
- 2 = 4y + 6 ( subtract 6 from both sides )
- 8 = 4y ( divide both sides by 4 )
y = - 2
Solution is (1, - 2 ) → B
