Answer:
This system of equations has no solution.
Step-by-step explanation:
Solving a system of equations can be done using a few different methods. Since your second equation is already solved for 'y', you can substitute this expression (-
x + 3) for the value of 'y' in the first equation:
2x + 4(-
x + 3) = 10
Distribute: 2x - 2x + 12 = 10
Combine like terms: 0 + 12 = 10 or 12 ≠ 10
Since the variables cancel out and 12 ≠ 10, there are no solutions to this system.
Answer:
15) x = 20
16) y = 45°, z = 30°
17) all 4 corners = 90°, all 4 sides are equal length, diagonals are perpendicular, diagonals bisect the corner angles.
We can't do the extra credit because we do not have a relationship about the side lengths. We just have angle information.
Step-by-step explanation:
15) 2x + 8 = 3x - 12
x = 20
16) 2y = 90°
y = 45°
3z = 90°
z = 30°
