The number of children in each family on a particular city block is shown in the dot plot: dot plot with number of children per family on the x axis and number of families on the y axis. 1 dot over 0, 3 dots over 1, 5 dots over 2, 2 dots over 3, 2 dots over 4, and 3 dots over 5 which histogram represents the dot plot data?

y -5 = (-1/4)(x + 8)

step-by-step explanation:

f(x)=2/3x-8, which give g(x) the greatest value.

step-by-step explanation:

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
