The function below models the correlation between the number of hours a plant is kept in sunlight (x) and the height (y), in mm, to which it grows: y = 2 + 4x what does the y0intercept of this function represent? the original height of the plant was 4 mm. the original height of the plant was 2 mm. the height of the plant increases by 2 mm for every hour of sunlight it receives. the height of the plant increases by 4 mm for every hour of sunlight it receives.

Add the fractions, and simply the result to lowest terms. 2/3 + 2/7= ?

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?
