Intro to Algebraic Review

Write in slope intercept form
5x - 3y = -9

• y = (5/3)x - 3
• y = (5/3)x + 9
• y = (5/3)x + 3
• y = (3/5)x + 3

What is the slope between the points
(-3, -4) & (7, 6)?

• 0
• Undefined
• -1
• 1

Simplify the exponential expression.

• 2x⁶y¹²
• 2x⁵y⁷
• 8x⁶y¹²
• 8x⁵y⁷

If f(x)=3x-9, find f(5).

• f(5) = 6
• f(5) = 16
• f(5) = -4
• f(5) = 24

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

• No solution
• n = 0
• All real solutions
• n = -2

Find the equation of the line shown

• y = 4x - 2
• y = -2x + 4
• y = 2x + 4
• y = -4x - 2

Write the equation of the line that goes through the points (4, 7) and (0, -5)

• y = 1/3x + 7
• y = 3x + 7
• y = 1/3x - 5
• y = 3x - 5

Write the equation of the line with slope = 5 and that goes through point (3, -5)

• y = 5x - 5
• y = 5x - 20
• y = 5x + 20
• y = 5x + 15

Solve for x:
4 - 5x < 22 - 2x

• x > -6
• x < -6
• x > 6
• x < 6

Simplify completely

• 3x⁵y⁷
• (1/3)x⁻⁷y⁵
• y⁵/3x⁷
• 1/3x²
