The temperature was 68°f. later that day the temperature was 82°f. how much does the temperature need to rise or fall to return to the original temperature of 68°f?

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

Solve this and show you’re work step by step ! -5 3/4+3h< 9 1/4 -
