Answer:

white 1: black 3

white 2: black 1

white 3: black 2

Step-by-step explanation:

white 1: the denominator for the x values so it becomes 1-2=-1 which becomes -1/3x +1/4

White 2: same case as the first so we add 1+2=3 3/3=1 so that makes it x+1/4

white 3: there is only one x values that has 4 as the denominator therefore that makes the answer 3/4x+1/3

Solve 5x^2 - 7x+2 -0 by completing the square. What are the solutions?

trapecia [35]

5x² - 7x + 2 = 0

5(x² - 7/5 x) + 2 = 0

5(x² - 7/5 x + 49/100 - 49/100) + 2 = 0

5(x² - 2 • 7/10 x + (7/10)²) - 49/20 + 2 = 0

5(x - 7/10)² - 9/20 = 0

5(x - 7/10)² = 9/20

(x - 7/10)² = 9/100

x - 7/10 = ± √(9/100)

x - 7/10 = ± 3/10

x = 7/10 ± 3/10

x = 10/10 = 1 or x = 4/10 = 2/5

Researchers have concluded that a dry basin began to fill with water in 1880. the water level rose an average of 1.6 millimeters

docker41 [41]

Answer:

the domain is [0,129]
112 mm
1942

Step-by-step explanation:

1. The function is good for years 1880 to 2009, 0 to 129 years after 1880. Values of x can be anything in the domain [0, 129].

2. 1950 -1880 = 70. The year 1950 corresponds to x=70, so the function tells us the water level rose ...

f(70) = 1.6·70 = 112 . . . . . mm

3. We want to find x when f(x) = 100. That will be the solution to ...

100 = 1.6x

100/1.6 = x = 62.5

Then 62.5 years after 1880 is year 1942.5. The water level was 100 mm higher than in 1880 in the year 1942.

An airplane has 29 seats. The price for a coach seat is $600 in the price for a first class seat is $1050. The airline collected

In-s [12.5K]

Answer:

19 coach seats

Step-by-step explanation:

let the number of coach seats be C and number of first class seats be F

given that the total number of seats is 29,

C + F = 29 ---------(eq 1)

also given that each coach seat = $600, each 1st class seat is $1050 and a total of $21900 was collected,

600C + 1,050F = 21,900 -------(eq 2)

we have 2 equations and 2 unknowns, we can solve the system of equations by elimination

(eq 1) x 1,050 gives us:

1,050 (C + F) = 1,050(29)

1,050C + 1,050F = 30,450 ----- (eq 3)

by elimination, subtract eq 2 from eq 3

(1,050C + 1,050F) - (600C + 1,050F) = 30,450 - 21,900

1,050C - 600C = 8,550

450C = 8550

C = 855 /450

C = 19
