A company manufactures and sells x VCRs per month. If the cost and revenue equations are C (x) = 400 + 4x, R (x) = 30x - x 2 40, use differentials to estimate the change, ∆P, in profit when the production is increased from 120 to 122.

Which equations are in standard form? Check all that apply y = 2x + 5 2x + 3y = - 6 - 4x + 3y = 12 y = y equals StartFraction 3 Over 2 EndFraction x minus 9. x - 9 StartFraction one-half EndFraction x plus 3 equals 6.
