An accountant charges an initial fee of $100 plus a rate of $40 per
hour. the function that shows the total fees charged
is f(x) = 40x+100 how would the graph of the function change if the
accountant raised his rate to $45 per hour?

b.-4 units

all you   do is count how many times you move

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

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
