Since there are 5 appetizers and 10 main courses, that already gives us 50 options. For each appetizer, you can pair it with ten different courses. That means for each appetizer, 10 options are possible. 10*5=50, so if there were only appetizers and courses, there'd be 50 choices. But there are also desserts. That gives us 2 times the possibilities (since for each previous possibility, you have two options for dessert). 2*50=100. There are 100 options.
No the square root of 9 is 3 or 3/1 which is a rational number. An irrational number cannot be written as a simple fraction
Since you have two known points, you can use the slope formula. This is (y2-y1)/(x2-x1), y2 being 12, y1 being 7, x2 being -39 and x1 being 26. So if you plug in the points it would be: (12-7)/(-39-26). This solved equals: -5/65 which simplified equals: -1/13. So the correct answer is A.
V-7=2/45
v=2/45+7
v=2/45+7/1
v=2/45+315/45
v=317/45
v=7.04
