An ice cream company uses two types of milk for its products. One type is 18% butterfat (x), and the other is 24% butterfat (y). Suppose that 42 gallons of ice cream containing 20% butterfat is made. Which system of linear equations can be used to find the
amount of each type of milk used in the mixture?

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)
