lisabon 2012 [21]

Answer:

52 cups

Step-by-step explanation:

1 gallon = 4 quarts

1.5 gallons = 6 quarts

6 + 9 = 13 quarts of lemonade in the fridge.

1 quart = 4 cups

13 quarts = 4 × 13 = 52 cups

52 cups of lemonade are in the fridge.

Answer:

$\displaystyle b = - 14$

$\displaystyle c = - 54$

Step-by-step explanation:

to figure out b we can consider the following formula:

$\displaystyle \frac{ - b}{2a} = h$

the form of vertex coordinate given by

$\displaystyle (h,k)$

so according to the question

$\displaystyle (h,k) = ( - 7, - 5)$

by order pair we obtain:

$\displaystyle h = - 7, k = - 5$

now substitute the value of h and a to the formula:

$\displaystyle \frac{ - b}{2(- 1)} = - 7$

simplify multiplication:

$\displaystyle \frac{ - b}{ - 2} = - 7$

cross multiplication:

$\displaystyle - b = 14$

divide both sides by -1:

$\displaystyle b = - 14$

now we need to figure out C to do so substitute -7 for x and -5 for y which yields:

$\displaystyle - {7}^{2} - 14( - 7) + c = - 5$

simplify square:

$\displaystyle -49 - 14( - 7) + c = - 5$

simplify multiplication:

$\displaystyle -49 + 98+ c = - 5$

simplify addition:

$\displaystyle 49+ c = - 5$

cancel 49 from both sides:

$\displaystyle c = - 54$

hence,

b=-14
C=-54
