for question 9: If B is 78 degrees then what is angle C and for question 10: if R is 86 then what is angle Q

Sate why the measure of angle d is 120 degrees

Suppose you want to transform the graph of the function y=tan(x+pi/4)-1 into the graph of the function y=-tan(x+pi/2)+1 which transformations should you perform. a) reflect the graph of the first function across the x-axis, translate it pi/4 units to the left, and translate it 2 units up. b) reflect the graph of the first function across the x-axis, translate it pi/4 units to the right, and translate it 2 units up. c) reflect the graph of the first function across the line y = -1, translate it pi/4 units to the left, and translate it 2 units up. d) reflect the graph of the first function across the line y = -1, translate it pi/4 units to the right, and translate it 2 units up.

The cost to rent a moving truck is a flat fee of $25 plus $0.60 per mile. the equation c = 25 + 0.6m models the cost, c, in dollars for the number of miles, m, traveled in the truck. identify the independent and dependent variables. the is the independent variable. the is the dependent variable.
