X²-4x+18=0

x= 4 ± √(16-4*1*18) / 2

x=4±√(16-72) /2

x= 4 ± √-56 /2

x = 4±2i√14 / 2

x= 2±√14 * i

Write an equation for a translation 1 unit down and 5 units right of y=|x|.<br> (y=[blank])
inn [45]

Answer:

Hence the corresponding equation of the given problem will be:

y'=|x-5|-1

Step-by-step explanation:

Let y' denote the corresponding equation after the translation of the given function y

We are given a equation of a function as:   y=|x|.

Now we have to write an equation such that there is a translation 1 unit down and 5 units right of y=|x|.

We know that for any function f(x) the translation 'a' units down is given by:

f(x)-a

And the translation 'b' units right of a function g(x) is given by:

g(x-b)

Hence the corresponding equation of the given problem will be:

y'=|x-5|-1

There are 45 students in the 6th grade at garden valley middle school. nine of them have freckles. what is the ratio of 6th grad
gulaghasi [49]

9 to 45 or 9:45 or 1:5. There are 9 students out of 45 students that have freckles. So there is 9 students with freckles to the total number of students which is 45. So it will be 9:45 or 1:5 if you simplify it.
