Question 1

What are the solutions to x squared minus 5x plus 6 = 0?

Accepted Answer

x = 2 and x = 3

Answer

Factor: (x-2)(x-3) = 0. Solutions are x = 2 and x = 3.

Question 2

Which of the following is the equation of a line perpendicular to y = 3x + 1?

Accepted Answer

y = -(1/3)x + 2

Answer

Perpendicular lines have slopes that are negative reciprocals. The slope of y=3x+1 is 3, so the perpendicular slope is -1/3. Only y = -(1/3)x + 2 has slope -1/3.

Question 3

If f(x) = 2x squared minus 3, what is f(-2)?

Accepted Answer

5

Answer

f(-2) = 2(-2)^2 - 3 = 2(4) - 3 = 8 - 3 = 5.

Question 4

A right triangle has legs of length 5 and 12. What is the length of the hypotenuse?

Accepted Answer

13

Answer

Using the Pythagorean theorem: c^2 = 5^2 + 12^2 = 25 + 144 = 169. c = sqrt(169) = 13.

Question 5

What is the simplified form of the square root of 72?

Accepted Answer

6 times square root of 2

Answer

sqrt(72) = sqrt(36 times 2) = sqrt(36) times sqrt(2) = 6*sqrt(2).
