For this item, enter the answers in the spaces provided. A swimmer is practicing for team tryouts and records the number of laps she swims and the amount of time it takes on four separate days. The table represents the
number of laps and the time taken to swim the laps on each of those days.

Complete the sentence.
To the nearest tenth, the equation for the line-of-best fit for the data is y=.+ and the best estimate for the amount of time, to
the nearest second, to swim 10 laps is
seconds.

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get

answer: graph 2
