Asystem of equations has 1 solution. if 4x – y = 5 is one of the equations, which could be the other equation? y = –4x + 5 y = 4x – 5 2y = 8x – 10 –2y = –8x – 10

What is the equation of the linear function represented by the table?

For which rational expression is -2 an excluded value of x?

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
