What is the inverse function of -5 (x-4) ^2+80
avanturin [10]
F(x)=-5(x-4)^2+80 
f(x)=-5(x²-8x+16)+80 
f(x)=-5x²+40x-80+80 
f(x)=-5x²+40x 

Replace f(x) to y, now switch the location of the variables x and y. Solve for new y. 

y=-5x²+40x 
x=-5y²+40y 
0=-5y²+40y-x 

Use quadratic formula to find the value of y. 

y=-40+-√(40^2 -4(-5)(-x)/2(-5)
f^-1(x)= (-40+-√1600-20x)/-10 <--- Not too sure about this one :/

Hope I helped :)

Use substitution to solve the system of equations.
gtnhenbr [62]
(3.75, 5.5)

(Work is attached )
When using substitution , you substitute with a variable that is already by itself. In this case, the variable “y” is already by itself and equal to x+ 1.75 . you substitute that for the the y in the other equation and solve for the other variable which is “x”. After you solve for x , to find your y value, you have to substitute the x value in for either equation.

In quadrilateral $ABCD$, we have $AB=3,$ $BC=6,$ $CD=4,$ and $DA=4$.
vampirchik [111]
The triangle inequality applies.

In order for ACD to be a triangle, the length of AC must lie between CD-DA=0 and CD+DA=8.

In order for ABD to be a triangle, the length of AC must lie between BC-AB=3 and BC+AB=9.

The values common to both these restrictions are numbers between 3 and 8. Assuming we don't want the diagonal to be coincident with any sides, its integer length will be one of ...
