Please solve. <br> Find the Inverse of x Squared<br> f of x equals 6 x + 2
frez [133]

Answer:

The function f of x equals 6 x + 2. First, replace the function notation f of x with y. y equals 6 x plus 2. Reverse the x and y variables. x equals 6 y plus 2. Solve for y by isolating it on one side of the equal sign. First subtract 2 from both sides of the equation. x minus 2 equals 6 y. Divide both sides by 6. The quantity of x minus 2 divided by 6 equals 6 y over 6. The quantity x minus 2 over 6 equals y. Replace y with the inverse function notation. The quantity of x minus 2 divided by 6 equals the inverse function of x. Now solve for the inverse function when x equals two. Substitute 2 for each x. The quantity of 2 minus 2 divided by 6 equals the inverse function of 2. Simplify. 0 divided by 6 equals the inverse function of 2. When x equals two, the corresponding y value on the inverse function is zero. 0 equals the inverse function of 2.

Which statement is true about the graphs of the two lines y= -4/5x + 2 and y = - 5/4x - 1/2?
vagabundo [1.1K]

They have no relation, except for the fact that they intersect.

We have given that,

The graphs of the two lines y= -4/5x + 2 and y = - 5/4x - 1/2

If the equations were instead y = +5/4x - 1/2 and

<h3>What is the slope of the perpendicular line?</h3>

Vertical lines and horizontal lines are perpendicular to each other. The slope of the perpendicular line in this case would be the slope of a horizontal line which would be 0. The slope of the parallel line is undefined and the slope of the perpendicular line is 0.

y = -4/5x + 2, or

y = +4/5 + 2 and

y = -5/4x -1/2,

Then they would be perpendicular.

a disinfectant spray bottle says it eliminate 90% of bacteria with each application. you apply the disinfectant onve to a counte
Novay_Z [31]
Well, I had to read twince to understand and Find out the answer!:D
XD
The answer would be 10% or 0%one of both
 :Because if you disinfected it once and what was left (if bottle is correct) is 10% of bacteria.
And you swiped it again, then there should be 0% of bacteria,because
 90%(first swipe)
=equals 10% left
 then another swipe
90% -the 10% left would mathamatically equal 10% Dont you think?
Im sure, not positive, but sure.
Am I right?
Hope this helped!
