Then divide it out:

Then, round to the second decimal point or the hundredths place:

D=2.92

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

i believe that the answer is

b. y-1=-2(x-4)

hope this !
