solve each system using substitution. 5. y=2x+5 y=6x+1 6. x=y+7 y-8=2x 7. 4x+y=2 3y+2x=-1 8. 4x+9y=24 y=-1/3x + 2

Reflect the point (7,0) across the y-axis

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
