Let a = and b = . determine if the equation ax = b is consistent for all possible b1, b2, b3. if the equation is not consistent for all possible b1, b2, b3, give a description of the set of all b for which the equation is consistent (i. e., a condition which must be satisfied by b1, b2, b3 ).

What is the range? can’t seem to find it out

Solve 2 - 3 cos x = 5 + 3 cos x for 0° ≤ x ≤ 180° a. 150° b. 30° c. 60° d. 120°

Titus works at a hotel. part of his job is to keep the complimentary pitcher of water at least half full and always with ice. when he starts his shift, the water level shows 4 gallons, or 128 cups of water. as the shift progresses, he records the level of the water every 10 minutes. after 2 hours, he uses a regression calculator to compute an equation for the decrease in water. his equation is w –0.414t + 129.549, where t is the number of minutes and w is the level of water. according to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
