Step-by-step explanation:
Answer:
The system of equations is:
x + y = 15
xy = 15
Step-by-step explanation:
solve the first for y and substitute in the second:
y = 15-x
x(15-x) = 15
15x - x� = 15
15x - x� - 15 = 0
-x� + 15x - 15 = 0
x� - 15x + 15 = 0
Answer:
D
Step-by-step explanation:
Because A isn' at all right and B, and C equal the same but D = 36 So the sides are 18 each side.
Answer:
1) 25x + 15y = 750
2) 25. On a graph it would look like : (25,0)
3) 15. On a graph it would look like : (15,0)
4) 25x - 750 = 15y or 15y - 750 = 25x
