Algebra 2

Find the x and y intercepts
4x - 5y = 40

• x intercept is 10 
  y intercept is 8

• x intercept is 10
  y intercept is 20

• x intercept is 8
  y intercept is 10

• x intercept is 10
  y intercept is -8

Solve for y:
3(y + 2) -16 = 8y

• y = -13/5

• y = -2

• y = 2

• y = -11/5

Solve for n:
6 - (8 - 4n) = 2(2n - 1)

• No solution

• n = 0

• All real solutions

• n = -2

Solve:
2x + y = 3
7x - 4y = 18

• (-30, -57)

• (1/2, 2)

• (2, -1)

• (21/5, -27/5)

Simplify: (x + 3) (x + 2)

• x² + 6x + 5

• x² + 5

• x² + 11

• x² + 5x + 6

Solve the proportion.

• k=5

• k=3.3333333

• k=60

• k=90

Which equation generates a graph containing
the set of ordered pairs shown below?
{(−15, 12), (−5, 8), (5, 4), (10, 2)}

• y = -3/5 x + 3

• y = -2/5 x + 6

• y = -1/5 x + 9

• y = -4/5 x

Which situation is best represented by the
function f(x), where f(x) = 12x + 5?

• An office-supply store sells x boxes of
  ballpoint pens that contain a dozen pens
  per box for $5 each.

• An Olympic swimmer trains by
  swimming 12 kilometers on each of x
  weekdays and 5 kilometers on each day
  of the weekend.

• An algebra quiz has x problems worth
  12 points each plus 5 extra-credit
  problems worth 5 points each.

• A company sells x baseball caps for $12
  each and charges a $5 shipping fee.

• y≥x−1
• y≤x−1
• y>x−1
• y≤x+1

• Function
• Not a Function
