The scatter plot below shows the increase in drive time for commuters from Oak Lawn to Chicago and the number of inches of snow that fell overnight. Determine the line of best fit for the data. y = 5.5x + 8.5 y = 2.8x + 10.5 y = 1.1x + 5 y = 0.95x + 12

you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

2x + 8

step-by-step explanation:

a.)the line for function b is steeper
