Solve for y:

8x + 4y = 16

• y = -8x + 16

• y = 2x -4

• y = -2x + 4

• y = -8x + 12

Combine like terms
3x + 2x + 3y - 7y

• 5x + 10y

• 5x + 4y

• 5x - 4y

• 5x -10y

What is the vertex of this equation?
y= x²+3x+5
Hint: find min in your calculator

• (1.5, -2.75)

• (1.5, 2.75)

• (-1.5, 2.75)

• (-1.5, -2.75)

Find the product:
(y - 3)(y + 7)

• y² - 21

• y² + 10x - 21

• y² + 4y - 21

• 2y - 10

Find the product:
(n - 5)(n - 1)

• n² - 5n + 5

• n² - 6n + 5

• n² + 5

• n² + 6n + 5

Multiply:
(r + 7)(r − 7) 

• r ² − 49 

• r ² + 14

• r ² − 7r + 49
