Question 3solve the problem. a moving firm charges a flat fee of $45 plus $40 per hour. let y be the cost in dollars of using the moving firm for x hours. find the slope-intercept form of the equation. ay = 40x + 45 by = 40x - 45 cy = 45x - 40 dy = 45x + 40

How to determine whether two known pairs of points are on the same line.

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6

James adds two numbers a + b. sally adds the same two numbers but reverse the order b + a what property of addition assures us that james and sally will get the same sum
