Question

Find the values of x that will return a profit. Assume the company has determined the cost equation to be C - 12.30x + 98,000 and the revenue generated by the sales is found to be R = 17.98x. A profit is made when the revenue is greater than the cost for x items. Find an equation of the line that passes through the point (1, -1) and has the slope m = 2 / 5. Find an equation of the line that passes through the points (12, 17) and (-12, -11) Find any intercepts: y = x2 - 11x + 24. Write an equation of the line that passes through the point (-9, 2) and is parallel to the line, 2x - 6y = -38. Write an equation of the line that passes through the point (-7, -9) and is perpendicular to the line, x = 1.

Explanation / Answer

4) 17.98 x = 12.3 x + 98000 x = 17254 items 5) y = mx + c y = 2/5 x + c (1,-1) -1 = 2/5 + c c = -7/5 5y = 2x - 7 6)(y-17) = (-11-17)/(-12-12) * (x- 12) 6y - 102 = 7x - 84 6y = 7x + 18 7)x^2 -11x +24 =0 (x-8)(x-3) =0 x= 3 and x=8 8)2x+6y = k -18 + 12 = k k =-6 2x+6y+6 =0 9) y = -9
