Answer:
Car 1 : 40 miles per gallon
Car 2: 25 miles per gallon
Step-by-step explanation:
family has two cars. During one particular week, the first car consumed 15 gallons of gas. The second car consumed 25 gallons of gas. The two cars Drove a combined total of 1475 miles and the sum of their fuel efficiency was 65 miles per gallon. What were the fuel efficiency of each of the cars that week
Given that :
Fuel efficiency , car 1 = x
Fuel efficiency , car 2 = y
x + y = 65 - - (1)
15x + 35y = 1475 - - - (2)
x = 65 - y
15(65-y) + 35y
975 - 15y + 35y = 1475
20y = 14875 - 975
20y = 500
y = 25
Put y = 25 in (1)
x + y = 65
x + 25 = 65
x = 65 - 25
x = 40
Answer:
<em>Axis of symmetry line is parallel to y- axis</em>
Equation of the parabola <em> ( x - ( -2 ))² = (y - 12 ) </em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given equation is y = x²+4 x+16
y = x²+2 (2 ) x + (2)² - (2)² + 16
y = ( x + 2 )² + 12
( x + 2 )² = y - 12
<em> ( x - ( -2 ))² = (y - 12 ) </em>
( x- h)² = 4 a ( y - k)
<em> Center (h ,k) = ( -2 , 12)</em>
<em> Here 4 a = 1 </em>
<em> a = 1/4</em>
<em>Focus S = ( h , K +a) = ( -2 , 12 + 0.25) = ( -2 , 12.25)</em>
<em>Axis of symmetry line is parallel to y- axis</em>
