Answer:
1 and -3
Step-by-step explanation:
The zeros of a quadratic function are the points on the graph where the curve intercepts the x-axis (where y = 0).
From inspection of the attached graph, we can see that the curve intercepts the x-axis at x = -3 and x = 1.
The six dollars for eight ounces is the cheaper one.
you have to find the common denominator between 5 and 8, the simplest I thought of was forty so to get the eight to forty, you multiply by five and six times five equals thirty and you do the same for the other one except it's times eight for this one so it'll equal thirty two, so there isn't much difference (two) but the first bottle has the lower unit rate
x lbs * 5.5 + 100 lbs * 6.25 = (x+100) * 6.00
distribute
5.5x + 625 = 6x+600
subtract 5.5 x from each side
625 = .5x +600
subtract 600 from each side
25 = .5x
divide each side by .5
x = 100
You need 100 pounds of the 5.50 mix
