Answer:
(-4, 15)
Step-by-step explanation:
The linear combination method involves combining the system of equations and eliminating one variable to solve for the other. In the given system, you need to first multiply one of the equations by -1 in order to eliminate the 'y':
-1(3x + y = 3) or -3x -y = -3
+ <u> 2x + y = 7</u>
-x = 4 or x = -4
Use x = -4 to solve for 'y':
2(-4) + y = 7 or -8 + y = 7
y = 15
Final answer: (-4, 15)
You must use Pythagorean theorem, which is
a and b are both legs (the two legs are the sides that form a perpendicular right angle) while c is the hypotenuse (side opposite the right angle)
In this case...
a = y
b = 8
c = 12
^^^Plug these numbers into Pythagorean theorem
Simplify as much as possible
+ 64 = 144
Isolate y by subtracting 64 to both sides
+ (64 - 64) = 144 - 64
= 80
Further isolate y by taking the square root of both sides. This will take away the square from the left side
y =
<<< Can be further simplified
4√5 = y
Hope this helped!
