What is the first step in solving the following equation?
3x - 5 = 20

• multiply both sides by 5
• add 5 to both sides
• divide both sides by 5
• subtract both sides by 5

Solve for a

• a= -2

• a= -7.5

• a= 2

• a= 6

Solve for a

• a= 9

• a= -9

• a= -5

• a= 5

Solve:
3(x - 2) = 18

• 6.7
• 4
• 8
• -4

5(x - 3) + 2x = 27

• 3
• 42/15
• 30/7
• 6

-4x + 14 ≤ 54

• x ≥ - 10
• x ≤ -10
• x ≥ 10
• x ≤ 10

-4x-7≥21

• x≥7
• x≥-7
• x≤8
• x≤-7

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

• D: {1, -3, -4,}
  R: {0, 1, 2, -4}
• D: {-4, 0, 1, 2}
  R:{-4, -3, 1}
• D: {0, 1, 2, 3, 4}
  R:{1, -3, -4}
• D: {0, 1, 2, -4}
  R: {1, -3, -4, 1}

• Function
• Not a Function

What is the range of the graph?

• 1 ≤ x ≤ 5
• 1 < x < 5
• 1 ≤ y ≤ 5
• 1 < y < 5
