Answer:
Step-by-step explanation:
well its 4.5-5.25= -0.75
I think it is asking for the answer, therefore it would be AB = 10.7

Answer:
(7, - 2 )
Step-by-step explanation:
Given the 2 equations
x = - 3y + 1 → (1)
- 3x - 3y = - 15 → (2)
Substitute x = - 3y + 1 into (2)
- 3(- 3y + 1) - 3y = - 15 ← distribute and simplify left side
9y - 3 - 3y = - 15
6y - 3 = - 15 ( add 3 to both sides )
6y = - 12 ( divide both sides by 6 )
y = - 2
Substitute y = - 2 into (1) for corresponding value of x
x = - 3(- 2) + 1 = 6 + 1 = 7
solution is (7, - 2 )
Answer: The helicopter is 8 miles from the landing pad.
The helicopter must fly to east to reach the landing pad.
Step-by-step explanation:The helicopter flies north which is upward for 4 miles, the southwest is at an angle downwards to the left for 9 miles. Overall the right hand triangle is formed, therefore we can use Pythagoras to solve for X.
r^2=x^2+y^2
r = 9
y = 4
Then x= 8.06
We moved y to the other side and solve for x and we placed square roots on both sides to solve for x.
The helicopter must move straight to the right to reach landing pad.
