The point-slope form of a equation of the line that passes through (-4, -3) and (12, 1) is y-1= 1/4 (x - 12) what is the standard form of the equation for this 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

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)
