For the inverse variation equation xy = k, what is the constant of variation, k, when x = 7 and y = 3?

I've never been good at math he told he loves but he keeps cheating on me, so it ain't adding up sis

The graph of h(x)= |x-10| +6 is shown. on which interval is this graph increasing

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.
