Answer:
(x, y) = (-6, 15) and (2, -1)
Step-by-step explanation:
You can start by subtracting the second equation from the first.
(y) -(y) = (x^2 +2x -9) -(-2x +3)
0 = x^2 +4x -12 . . . . . . collect terms
0 = (x +6)(x -2) . . . . . . . factor
Solutions for x are -6 and +2. These values make the factors zero.
The corresponding solutions for y are ...
y = -2(-6) +3 = 15
y = -2(2) +3 = -1
Solutions to the system of equations are ...
(x, y) = (-6, 15) and (2, -1)
Answer:
6 is the integer which is equivalent to 9 and 3 halves
Step-by-step explanation:
we have to find the integer which is equivalent to 9 and 3 halves
Rule of halves means the restatement of meaning of median. Therefore, we have to find the median of these two integers 9 and 3.
Median of 9 and 3 is
Hence, 6 is the integer which is equivalent to 9 and 3 halves
