Answer:
you have to have a fighting spirit
Step-by-step explanation:
The system of equations provides a unique solution(one solution) at (-0.6, 1.6).
<h2>Given to us,</h2>


<h3>Equation 2</h3>
As we already have the value of y from equation 1, substitute its value in equation 2,








<h3>Equation 1,</h3>

substitute the value of x in equation 1,

As we can see the system of equations provides a unique solution(one solution) at (-0.6, 1.6).

When one (not two!) of them is negative:
for example the product of -1 and 6 is -6, which is less than both factors.
It's equal to both factors when they're both 1:
1 x 1=1
Answer:
Angle of elevation of the airplane = 17.46 degrees
Step-by-step explanation:
From the picture attached,
An airplane is flying at an altitude of 1500 ft at point A.
Runway starts from point B from which distance of the airplane is 5000 ft.
Now we apply sine rule in the given triangle ABC to measure the angle θ.
sinθ = 
sinθ = 
= 

degrees
