TSIA2 Algebra Fundamentals 2

Question 1

Which value of x satisfies the equation 3(x - 4) = 2x + 1?

Accepted Answer

x = 13

Answer

Distributing gives 3x - 12 = 2x + 1, so x = 13.

Question 2

What is the slope of the line passing through (2, 5) and (6, 13)?

Accepted Answer

2

Answer

Slope = (13 - 5) / (6 - 2) = 8 / 4 = 2.

Question 3

Which expression is equivalent to (x + 3)(x - 5)?

Accepted Answer

x² - 2x - 15

Answer

Using FOIL: x² - 5x + 3x - 15 = x² - 2x - 15.

Question 4

A car rental costs $30 per day plus $0.15 per mile. If Maria paid $67.50 for one day, how many miles did she drive?

Accepted Answer

250 miles

Answer

0.15m = 67.50 - 30 = 37.50, so m = 250 miles.

Question 5

What is the y-intercept of the line 4x - 2y = 8?

Accepted Answer

y = -4

Answer

Solving for y: y = 2x - 4, so the y-intercept is -4.
