b)y-10= 5/2(x-2)

c)y-2=5/2(x-1)

d)y-15=5/2(x-4)

Solve for x -2.3(r - 1.2 ) = -9.66 enter you answer as decimal.

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
