Answer:
71
Step-by-step explanation:
Set up proportions.
3/4 cups → 1 batch
x cups → 2 batches
x = 2(3/4) = 6/4 = 1 1/2 cups
3/4 cups → 1 batch
y cups → 9 batches
y = 9(3/4) = 6 3/4 cups
The equation is y= -2x + 3.
The 3 is the y-intercept and how I got -2 was that I did rise/run. It went down 2 times and over once so -2/1, which will give you simply -2.
Sin 2A + sin 2B = 2sin(A+B) cos(A-B)
sin 2A - sin 2B = 2cos(A+B)sin(A-B)
dividing both...
(2sin(A+B) cos(A-B)) / (2cos(A+B)sin(A-B))
= (sin(A+B)cos(A-B))/(cos(A+B)sin(A-B))
=tan(A+B) X cot(A-B)
=tan (A+B) / tan(A-B)
