Movie Ticket Sales : 6x + 9y = 1,500 Which graph shows this relationship?
sukhopar [10]
Ok so we have movie ticket sales and we have 6x+9y=1,500. So for types of graphs, we have linear, exponential, quadratic, and those are the basic types of graphs. Now looking at the equation, we can quickly see that the answer is linear because, looking at the constant, 1500 and the other numbers, we can see the graph will be increasing linear. Hope this helped, feel free to ask questions if you have any!

I have two proof questions and I don't really know how to do them.
goldfiish [28.3K]

\angle1\cong\angle2 corresponding angles, therefore

m∠1 = m∠2 → m∠2 = 130°

\angle2\cong\angle3 vertical angles, therefore

m∠2 = m∠3 → m∠3 = 130°


If ∠1 and ∠2 are complementary, then m∠1 + m∠2 = 90°.

If ∠2 and ∠3 are complementary, then m∠2 + m∠3 = 90°

Therfore

m\angle1 + m\angle2 = m\angle2 + m\angle3\qquad|\text{subtract}\ m\angle2\ \text{ from both sides}\\\\m\angle1 = m\angle3\to\angle1\cong\angle3
