TTCM Multiple Choice Review

Front

Find the slope between two points (x1, y1) and (x2, y2).

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

Simplify the radical expression √a.

Back

To simplify √a, factor a into its prime factors and pair them. For example, √24 = √(4*6) = 2√6.

Front

What is the sum of two complex numbers (a + bi) and (c + di)?

Back

The sum is (a + c) + (b + d)i.

Front

How do you solve for a variable in an equation?

Back

Isolate the variable on one side of the equation using inverse operations.

Front

What does it mean to solve an inequality?

Back

To solve an inequality means to find the range of values that satisfy the inequality condition.

Front

What is the formula for the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you simplify the expression 2√a * 3√b?

Back

Multiply the coefficients and the radicals: 2 * 3 * √(a * b) = 6√(ab).

Front

What is the conjugate of a complex number a + bi?

Back

The conjugate is a - bi.

Front

How do you find the x-intercept of a linear equation?

Back

Set y = 0 in the equation and solve for x.

Front

What is the quadratic formula?

Back

The quadratic formula is x = (-b ± √(b² - 4ac)) / (2a) for the equation ax² + bx + c = 0.
