Carlita saw 5 times as many robins as cardinals while bird watching. She saw a total of 48 birds.
zhannawk [14.2K]

Answer:

42 more

Step-by-step explanation:

Let carlita saw x and cardinals saw y robins.

According to question,

x=5y....(1)

and

x+y=48...(2)

Put the value of x from equation (1) in equation (2)

So,

5y+y=48

6y=48

y=8

Put y = 8 in equation (1).

x=5(8) = 40

Hence, Carlita see 42 more robins than Cardinals.

Convert the equation to the standard form for a parabola by completing the square on x or y as appropriate.
RideAnS [48]
Y² + 2 y - 2x - 3 = 0
x + 3 = y² + 2 y
2 x + 3 = y²  + 2 x + 1 - 1
2 x + 3 = ( y + 1 )² - 1
2 x + 3 + 1 = ( y + 1 )²
Answer:
2 ( x + 2 ) = ( y + 1 )²
