本文主要是介绍两道SAT数学试题及其解析，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
下面是两道关于代数方面的SAT数学试题及其解法。SAT数学试题的解答是虽然相对比较简单，但是需要大家熟悉并且掌握其特别的出题方式和解题的思路，这样才能更快更好的解答SAT数学题。下面我们就来看看这两道SAT数学试题的解法吧。
1.Which of the following lines is perpendicular to y = 3x + 4 and has 6 for its x-intercept? (Ay = 3x – 6 (By = –3x + 6 (Cy = – x + 6 (Dy = – x – 2 (Dy = – x + 2 Correct Choice:E Explanation:The slope of y = 3x + 4 is 3. A line perpendicular to this line has a slope that is the opposite of the reciprocal of 3, or –1⁄3. If the x-intercept of the desired line is 6, then the line contains the point (6, 0, and we have enough information to put it in point-slope form: (y – 0 = –1⁄3(x – 6. This simplifies to y = –1⁄3 x + 2. The following equation represents which type of graph? 2y = –6x2+ 24x – 12 (AA parabola that opens downward with vertex (–2 ,6 (BA parabola that opens upward with vertex (6, 2 (CA parabola that opens upward with vertex (–2, –6 (DA parabola that opens downward with vertex (2, 6 (DA parabola that opens downward with vertex (–6, 2 Correct Choice:D In this equation, y is raised to the first power, and x is squared. This should lead you to believe that the graph of this equation is a parabola (in the equation of a circle, both variables are squared. Simplify the equation to arrive at the standard form: 2y=-6x2+24x-12 Y=-3x2+12x-6 Y=-3(x2-4x-6 Y=-3(x2-4x+4-6+12 Y=-3(x-22+6
The equation in the question is the standard form of a parabola. From it we can see that –3 < 0, so the parabola opens downward, and the vertex is (2, 6.
