Ship a has coordinates (-1, -2) and ship B has coordinates (-4, 1). Both ships have their spotlights fixated on the same lifeboat. The light beam from ship A travels along the line y=2x. The light beam form ship B travels along the line y=x+5. What are the coordinates of the life boat

Y=4x^2+x-1 solve using quadratic formula

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label

Average acceleration: i have no idea how to do this.
