2 is b
3 is d
4 is a
Step-by-step explanation:
Open circle is 'less than' or 'greater than'.
Closed (shaded) circle is 'less than or equal to' or 'greater than or equal to'.
I think it’s 20, the 0 to 4 is 9 and the 5 to 9 is 11, 9 + 11 = 20
Solve for y in one of the equations.
4x + y = 11
Subtract 4x from both sides.
y = -4x + 11
Substitute y in the other equation.
8x + 2(-4x + 11) = 13
Simplify.
8x + -8x + 22 = 13
Subtract 22 from both sides.
0 = -9
No solutions.
