The discriminant of 2x^2 + 3x + 1 = 0 is -2
True
False
2x^2 + 3x + 1 = 0 has 2 REAL solutions.
Solve 6x^2 - 13x - 8 = 0 by factoring.
x = 1/2; x = -8/3
x = -1/2; x = 8/3
x = 1; x = 3
Solve: 4 - 5x = 3x + 14
x = -5/2
x = 5/4
x = -5/4
Solve: - 2x + 7 < 5x + 1
x > 6/7
x < 6/7
x > - 6/7
The length of a rectangle is 9 feet less than twice the width. The perimeter is 54 ft, find the width and length.
w = 12 l = 15
w = 9 l = 36
w = 6 l = 42
Force, f, is directly proportional to the acceleration, a. If a force of 10 pounds produces an acceleration of 2 feet per second, what will be produced by a 15- pound force?
The acceleration for a 15-pound force is 3 feet per second.
