Answer:
No
Step-by-step explanation:
To determine if the point (- 3, 5) is a solution to both equations.
Substitute the x and y values into the left side of both equations and if equal to the right sides then the point is a solution.
x - 3y = - 3 - 3(5) = - 3 - 15 = - 18 ← True
- 2x + y = - 2(- 3) + 5 = 6 + 5 = 11 ← False
Thus (- 3, 5) is not a solution to the system of equations.
Answer:
170°
Step-by-step explanation:
To convert from radians to degrees
degree measure = radian measure ×
, thus
degree =
× 
Cancel π on numerator/denominator and 18/ 180 by 18
degree measure = = 17 × 10 = 170°

Answer:
The distance of the helicopter from the bristol is approximately 1<u>2.81 miles</u>
Step-by-step explanation:
Given:
Helicopter flies 10 miles east of bristol.
Then the helicopter flies 8 miles North before landing.
To find the direct distance between the helicopter and bristol.
Solution:
In order to find the distance of the helicopter from the bristol before landing, we will trace the path of the helicopter
The helicopter is first heading 10 miles east of bristol and then going 8 miles due north.
On tracing the path of the helicopter we find that the direct distance of the helicopter from the bristol is the hypotenuse of a right triangle formed by enclosing the path of the helicopter.
Applying Pythagorean theorem to find the hypotenuse of the triangle.



Taking square root both sides.

Thus, the distance of the helicopter from the bristol is approximately 12.81 miles
