I really need help with this The Trailblazer Diner serves hotdog plates for $4.50 each and hamburger plates for $6. If 512 students bought lunch from the diner and the total revenue from the sale of the plates was $2,580, then how many hotdog plates were sold, and how many hamburger plates were sold?

True or false: the graph of y=f(bx) is a horizontal compression of the graph y=f(x) if b< 1

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.

Which graph has a rate of change of zero
