If f(x) = 2x + 1, what would be your first step to find f(1)?

• Plug a 1 in for all the x's

• Set the function equal to 1

• Only plug a 1 into the left side

• Only plug a 1 into the right side

Given f(x) =
2x² + 5x - 17, find f(-1). 

• f(-1) = -20
• f(-1) = -24

54x + 64 ≥ 49x + 59

• x≥−1
• x≤-1
• x>9
• x<-3

Yellow Cab Taxi charges a $1.75 flat rate in addition to $0.65 per mile.  Katie has no more than $10 to spend on the taxi ride.

• 1.75 + 0.65m < 10
• 1.75 + 0.65m > 10
• 1.75m + 0.65 < 10
• 1.75m + 0.65 > 10

Factor
3v² - 4v - 7

• (3v-7)(v+1)
• 3(v-7)(v-1)
• (3v+1)(v-9)
• (3v+1)(v-10)

Factor
4n²-17n-15

• (n-10)(6n+1)
• (4n-5)(n-3)
• (n-5)(4n-3)
• (n-5)(4n+3)

Write the slope-intercept form of the linear inequality -2x + 5y < 10.

• y > (2/5)x - 2

• y < (2/5)x - 2

• y < (2/5)x + 2

• y > (2/5)x + 2

Convert the linear inequality 4x + 3y ≤ 12 from standard form to slope-intercept form.

• y ≥ (-4/3)x + 4

• y ≤ (-4/3)x + 4

• y ≤ (4/3)x + 4

• y ≥ (-4/3)x - 4
