(30 points, again) An air traffic controller is tracking two planes. To start, Plane A is at an altitude of 3015 feet and Plane B is just taking off. Plane A is gaining altitude at 30.5 feet per second and Plane B is gaining altitude at 80.75 feet per second. How many seconds will pass before the planes are at the same altitude? (in seconds) What will their altitude be when they're at the same altitude? (in feet)

Can someone me do math because i am having a breakdown rn because i don’t get it

(co 3) the soup produced by a company has a salt level that is normally distributed with a mean of 5.4 grams and a standard deviation of 0.3 grams. the company takes readings of every 10th bar off the production line. the reading points are 5.8, 5.9, 4.9, 6.5, 5.0, 4.9, 6.2, 5.1, 5.7, 6.1. is the process in control or out of control and why? it is out of control as two of these data points are more than 2 standard deviations from the mean it is in control as the data points more than 2 standard deviations from the mean are far apart it is out of control as one of these data points is more than 3 standard deviations from the mean it is in control as the values jump above and below the mean

Write the equation of the line that passes through (3, 4) and (2, −1) in slope-intercept form. (2 points) y = 3x − 7 y = 3x − 5 y = 5x − 11 y = 5x − 9
