Answer:
1) 4 bottles
2) $0.75
3) $5.25
Step-by-step explanation:
1)9/3 = 3 so you must divide 12 by 3
12/3=<u>4 bottles</u>
2)12/1=12
divide 9 by 12
9/12 =<u>$0.75</u>
3)12/7 = (The actually number is too long to write so just leave it in fraction form)
9÷12/7=<u>$5.25</u>
=======================================================
Explanation:
If we plugged x = 3 into the expression, then we'd get x-3 = 3-3 = 0 in the denominator. That's not allowed. But we can simplify first
x^2-x-6 factors to (x-3)(x+2). The key here is that (x-3) is a factor. It cancels with the x-3 in the denominator
So,
Allowing us to say,
One leg is horizontal, on the line y=3. Another leg is vertical, on the line x=1. The point where these intersect, D(1, 3) is the vertex of a right angle. Any right triangle inscribed in a circle has its hypotenuse as the diameter of the circle.
Since the triangle is a right triangle, the circumcenter is the midpoint of the hypotenuse: ((8, 3) + (1, -5))/2 = (4.5, -1).
