Julie is going to a store to buy vases to use as centerpieces at her party. small vases cost $2 and large vases cost $4. she needs to buy a minimum of 15 vases, and can spend a maximum of $50. which system of linear inequalities represents this situation? let s represent the number of small vases and l represent the number of large vases. a s + l ≥ 15 2s + 4l ≤ 50 b s + l ≤ 15 2s + 4l ≥ 50 c s +l ≥ 50 2s + 4l ≤ 15 d s + l ≥ 15 2s +4l ≥ 50

City l has a temperature of −3 °f. city m has a temperature of −7 °f. use the number line shown to answer the questions: number line from negative 8 to positive 8 in increments of 1 is shown. part a: write an inequality to compare the temperatures of the two cities. (3 points) part b: explain what the inequality means in relation to the positions of these numbers on the number line. (4 points) part c: use the number line to explain which city is warmer. (3 points)
