Answer:
(y - 1)(5y - 2)

Solution:

Factor:
2 - y(7 - 5y)

Apply the Distributive Property:
2 - 7y + 5y²

Reorder the expression:
5y² - 7y + 2

Rewrite the term:
5y² - 5y - 2y + 2

Regroup terms into two proportional parts:
(5y² - 5y) + ( -2y + 2)

Factor Greatest Common Factors out:
5y(y - 1) - 2(y - 1)
(y - 1)(5y - 2)

On a certain hot summer's day, 643 people used the public swimming pool. The daily prices are $1.50 for children and $2.00 for

lilavasa [31]

249 children and 394 adults swam at the public pool.

Step-by-step explanation:

Number of people swam at pool = 643

Receipts = $1161.50

Cost for one child = $1.50

Cost for one adult = $2.00

Let,

x be the number of children

y be the number of adults

According to given statement;

x+y=643 Eqn 1

1.50x+2.00y = 1161.50 Eqn 2

Multiplying Eqn 1 by 2

$2(x+y=643)\\2x+2y=1286\ \ \ Eqn\ 3\\$

Subtracting Eqn 2 from Eqn 3

$(2x+2y)-(1.50x+2.00y)=1286-1161.50\\2x+2y-1.50x-2.00y=124.50\\0.5x=124.50$

Dividing both sides by 0.5

$\frac{0.5x}{0.5}=\frac{124.50}{0.5}\\x=249$

Putting x=249 in Eqn 1

$249+y=643\\y=643-249\\y=394$

249 children and 394 adults swam at the public pool.

Write the slope-intercept form of the equation of the line through the given point with the given

alekssr [168]

Answer:

6) y = -7x +11

8) y = -1/3x -1

10) y = 5/4x -2

Step-by-step explanation:

It is convenient to start with a point-slope form of the equation.

y = m(x -h) +k . . . . . line with slope m through point (h, k)

6) m = -7, (h, k) = (2, -3)

y = -7(x -2) -3 = -7x +14 -3

y = -7x +11

8) m = -1/3, (h, k) = (-3, 0)

y = (-1/3)(x -(-3)) +0

y = -1/3x -1

10) m = 5/4, (h, k) = (4, 3)

y = 5/4(x -4) +3 = 5/4x -5 +3

y = 5/4x -2
