Astudent received the following grades last semester. find the student's semester grade point average. an a is algebra (3 credits), a b in history ( 3 credits), a in sociology ( 3 credits) a d in english ( 3credits) and a c in seminar ( 2credits). an a is worth 4 points, a b is worth 3 points a c is worth 2 points and a d is worth 1 point.

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1

Find the solution(s) to the system of equations. select all that apply y=x^2-1 y=2x-2
