Since there are 4 quarts in a gallon, 8 quarts equals 2 gallons
Answer:
D
Step-by-step explanation:
3/4 everything else is a whole number
Let x be the number of representatives
Y be the number of members in united states senate
Representatives
has 35 more members than four times the number of members in the united states senate
X = 4y + 35
x = 4(100) + 35
<span>x = 435 number of members in the house</span>
Discount = 28.00 - 22.95 = $5.05
Percent saved = 5.05*100 / 28 = 18.04% <-----
Vertex form of the equation:
y = a ( x - h )² + k;
15 = a ( 0 - 4 )² - 1
15 = 16 a - 1
16 a = 16
a = 16 : 16
a = 1
After that we have to transform the equation to the standard form:
y = ( x - 4 )² - 1
y = x² - 8 x + 16 - 1
y = x² - 8 x + 15
Finally we have to find the zeroes:
x² - 8 x + 15 = 0
x² - 5 x - 3 x + 15 = 0
x ( x - 5 ) - 3 ( x - 5 ) = 0
( x - 5 ) ( x - 3 ) = 0
x = 3, x = 5
Answer:
( x 1, y 1 ) ; ( x 2 , y 2 ) = ( 3, 0 ) ; ( 5 , 0 )
