The table shows the number of households with a telephone answering machine in selected years after 1980. 4 6 8 10 12 16 18 Years after 1980 (x) Number of Households with Answering Machines 8.7 10.8 13.0 16.0 21.0 30.0 37.5 43.8 Using the data points, which quadratic equation best models this set of data? Oy = -0.008x2 + 0.79x – 1.39 y = 0.15.x2 – 0.74x + 9.25 Dy = 8.4x2 – 0.6x + 7.3 y = 0.2x2 – 1.5x + 12

step-by-step explanation:

milk=16 large

soda=280 kids

juice box=82 regular

63 soda +63 regular

124 large total

3 is greater then both of those numbers

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
