At 1:40 PM, the temperature is 99˚F. For the rest of the evening, the temperature drops an average of 4˚F per hour. Write an equation in slope-intercept form to represent the temperature y after x hours.

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.)

Divide. reduce the answer to lowest terms.5 2/3 ÷ 3 1/9

Anyone? 15m is what percent of 60m; 3m; 30m; 1.5 km?
