Answer:
x=10
Step-by-step explanation:
you know that 12x+5+6x-5=180 you can simplify the equation to 18x=180 and then you can divide both sides by 18 to get that x=10
20+36= 56
56+20=76
she drank 76 ounces
and there are 8 ounces in a cup
76÷8=9.5
she drank 9.5 cups
According to the vertical angle rule we know that x is 40 degrees. The sum of all angles in a triangle make 180, so the sum of x, 60, and the third angle is 180. x is 40 so the third angle is 180-60-40 which is 80 degrees. y is an adjacent angle, which means that the sum of y and 80 degrees is 180. 180-80 is 100, so y is 100 degrees.
we know that
the equation
describe a vertical parabola with vertex at point 
if 
-------> the parabola open Up and the vertex is a minimum
if 
-------> the parabola open Down and the vertex is a maximum
in this problem we have
---> because is positive (given problem)
so
The vertex is a minimum
therefore
<u>the answer is the option C</u>
Up
