Answer:
C
Step-by-step explanation:
Given the 2 equations
y = x + 2 → (1)
- x + 3y = 6 → (2)
Substitute y = x + 2 into (2)
- x + 3( x + 2) = 6 ← distribute left side
- x + x + 6 = 6, that is
6 = 6 ← True
This statement indicates the system has infinitely many solutions
The given curve crosses the x-axis in two places, (-2, 0) and (0, 0), which are the zeros. This parabolic curve opens up and has its vertex (minimum) at (-1, -1).
The answer is 60
It would be 10 because 13 is not greater than or equal to 15
