Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?

If the discriminant if a quadratic equation is 4 which statement describes the roots?

Which is an x-intercept of the graphed function? (0, 4) (–1, 0) (4, 0) (0, –1)
