Answer:
The values of x and y to the given equations are x=-1 and 
The solution is (-1,
)
Step-by-step explanation:
Given equations are 
and 
to solve the given equations by elimination method :
Adding the given two equations (1) and (2) we get
_______________
4x=-4
Therefore x=-1
Now substitute the value x=-1 in equation(1) we get
(-1)+3y=9
3y=9+1
Therefore the values of x and y to the given equations are x=-1 and
The solution is (-1,)
Hello! We will be using the Pythagorean theorum, where a² + b² = c². C is the clanted part of the triangle, and 13² is 169. a = 12, and we are looking for the value of b. 12² is 144. Let's subtract to find b. 169 - 144 is 25. Now, let's find the square root of 25 to find the length. √25 is 5. There. b = 5. The side length of side b is 5. The correct answer is C: 5.
Answer:
