How do you simplify this by "rationalizing the denominator"?
Write 37.5% as a fraction
Use the discriminant to determine how many real-number solutions the equation has.
1 - 7a² = -7a - 2
Since the quadratic formula when used to solve quadratic equations always spits out the correct answer, why do we not use only this method rather than even bothering with the other methods?
Which equation represents a line that contains the point (6,8) with a slope of 5?
Two angles are complementary. The sum of the measurement of the first angle and half the second angle is 84. Find the measures of the angles. What is the measure of the smaller angle? What is the measure of the other angle?
