Answer:
A. Exactly one solution
Step-by-step explanation:
Solve the system of equations.
y = x + 1
y = 2x - 5
Substitute one equation into the other.
y = 2x - 5
x + 1 = 2x - 5
Subtract 2x from both sides.
-x + 1 = -5
Subtract 1 from both sides.
-x = -6
Multiply both sides by -1.
x = 6
Put it back into the other equation.
y = x + 1
y = 6 + 1
Add.
y = 7
The solution is (6, 7). Since the equations aren't equal, there are not infinitely many solutions, but since there is a solution found, we can determine that there is exactly one solution.
Answer:
y - 5 = (-4)( x - 2 );
y - 5 = -4x + 8;
y = -4x + 13 is the standard form of the equation for the line;

Answer:
A) 30°
Step-by-step explanation:
All triangles angles add always to 180°, so we have two already 75° + 75° = 150° thus the angle is 30°
