Triangle def has coordinates d(–3, –2), e(–1, –2), f(–2, –4). the triangle is translated so its image has coordinates d'(1, –4), e'(3, –4), f'(2, –6). which statement shows the rule for the translation? (x, y) (x – 4, y – 2) (x, y) (x – 4, y + 2) (x, y) (x + 4, y + 2) (x, y) (x + 4, y – 2)

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 9 + 12x + 4x^2

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (–4, 0) and (6, 0). the y-intercept of the first parabola is (0, –12). the y-intercept of the second parabola is (0, –24). what is the positive difference between the a values for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth

Agroup of student volunteers participates in a study designed to assess several behavioral interventions for improving output in a repetitive task. prior to the beginning of the study, all volunteers unknowingly observed, and their output is measured. at the beginning of the study, prior to any intervention, the volunteers perform the same task under the observation of a study administrator, and their overall output increases. which of the following terms describes this phenomenon? a. simpson's paradox b. hawthorne effect are d. novelty effect d. pygmalion effect e. observer-expectancy effect
