Warm Up #1 A line in the xy-plane has a slope of 1/9 and passes through the point (0,14). Which equation represents this line? A. y = (-1/9)x – 14 B. y = (-1/9)x + 14 C. y = (1/9)x – 14 D. y = (1/9)x + 14 Warm Up # 2 If x/8=5, what is the value of 8/x? Warm Up #3 Triangles ABC and DEF are congruent, where A corresponds to D, and B and E are right angles. The measure of angle A is 18°. What is the measure of angle F? A. 18°. B. 72°. C. 90°. D. 162°. Problem 1 y = x^2 – 14x + 22 The given equation relates the variables x and y. For what value of x does the value of y reach its minimum? Problem 2 The measure of angle R is 2π/3 radians. The measure of angle T is 5π/12 radians greater than the measure of angle R. What is the measure of angle T, in degrees? A. 75 B. 120 C. 195 D. 390 Problem 3 What is the smallest solution to the given problem? Problem 4

Day 1: Practice Problems

Question 1 The table summarizes the distribution of color and shape for 100 tiles of equal area. If one of these tiles is selected at random, what is the probability of selecting a red tile? What is the probability of selecting a blue tile? Question 2 From a population of 500 people, 100 were chosen at random and surveyed about a proposed piece of legislation. Based on the survey, it is estimated that 20% of people in the population support the legislation, with an associated margin of error of 1%. Based on these results, which of the following is a plausible value for the total number of people in the population who support the proposed legislation? A. 20 B. 90 C. 98 D. 120 Question 3 What is the positive solution to the given equation? Question 4 A rectangle has a length of x units and a width of (x – 15) units. If the rectangle has an area of 76 square units, what is the
