Please help its my final!!
also if you can provide steps how you done it can be really helpful

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2

Which expressions equal 9 when x=4 and y=1/3 a. x2+6y b. 2x + 3y c. y2-21x d. 5 (x/2) -3y e. 3x-9y

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.
