Use a number line to approximate the value of √51

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

Write as a product: ac^2–ad+c^3–cd–bc^2+bd

What is the slope of any line parallel to the line 8x+9y=3 in the standard (x,y) coordinate plane?
