Newtons first law is often called “the law of inertia”. how does this law apply to the car’s motion when you changed the mass but kept the force constant?

The system of equations graphed below has how many solutions?

Which of the following is the shape of a cross section of the figure shown below

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
